1. your build has 4 medium pulse lasers and 2 SSRM 2's.
a medium pulse laser does slightly more damage, DPS, and shorter beam length for more weight (for this case it's double the weight of a normal medium laser) thus it does suck up a bit of tonnage. I should also mention that tonnage (4 tons) could have went for 1 more medium laser and a bigger engine. I also should mention you got 2 SSRM 2's, an SSRM 2 is more heavier for the guidence system (streak) which allows it to lock on ,fire, and then forget. as well as high chance of hitting an enemy and follow the target but compared to a normal SRM 2 it's just heavier if you can aim well, SSRM's is typically good for when targeting faster mechs. Thus you do not handle yourself to well with the bigger folks with this.
overall your firepower is a bit low on your build, XL engine has trade ofs but if you can roll your damage you can avoid the ST destruction longer. Also an XL engine opens up tons that is often making you a colder mech as well as faster, more firepower, or both, which can be usefull, normally for a hunchback XL is a no no due to your hunch and the fact you can still fight with your head laser BUT the hunchback 4SP has smaller hunchies to basically non existance. so you can trade for an XL engine.
In this game you got this thing called quirks, they change some stuff but for inner sphere mostly adds structure/ armour and change weapon characteristic,

ENERGY HEAT GENERATION: -10.00 %
This is the current quirks. Missile cooldown and SRM 6 cooldown stack, for 40% faster cooldown (aka fire rate, you fire 40% more faster) and also your medium lasers is 20% colder while your medium pulse is 10% colder as it isn't a medium laser.
HBK-4SP build is an example what you can do. it can hit much more harder and with speed tweak it can run 98 kph so in this instance at least you can out gun anything that out runs you.
This specific build is also quite cool (literally) and if you want you can remove some DHS and drop the artemis for AMS or something. some practice with the XL engine can help a long way.
I should mention however quirks will be rebalanced soon and from the current looks no weapon quirks will be out anymore, however it doesn't matter to much as I used a build much like this before quirks came out!
Your current build if you want it to be all pulsy and streaks would be better on a different mech but if you wnat it on the hunchback you can go for a this
HBK-4SP I just built... it doesn't use the focused quirks but still use the generic quirks. It hits harder with the lasers now and can catch up to the lights so it may be better to use against the smaller guys.
Hunchback as a rule of thumb often use bigger mechs and help them out so they do not take to much damage but dish out a lot, this is more true with the 4G, 4H, and the hero but the 4P, 4SP, etc also may follow a similar attack pattern. So going toe to toe isn't the best option with anything bigger then you but if you do end up in that situation try focusing your firepower to bring down the mighty foe.
2. awesome in lore is a PPC boat and is prone to being very week up close due to the fact it's sniper gear is not that good up close, because it's range and damage and heat is good at range compared to other waepons but up close 2 medium lasers for 2 tones, 2 slots, and much less heat does the same damage as a ppc at 7 tons, 3 slots, etc. So the awesome (quirks and lore and kinda MW: O ) is best at range, across all variants LRM's, PPC's, ER PPC's, and mixed ER/PPC + LRM builds work well BUT you can try your hand in with SRM/ Large pulse brawly builds, this mech isn't the best at brawling due to profile but some say it doesn't matter while due to it's profile you can easily turn at rather range or up close to take the damage to the arm. Light mechs is the bane of most bigger mechs as they can out manuver you and kill you if you are not careful so try to stick with the team.
3. Nova is a clan omnimech, omnimech rules in MW: O makes it a bit of a 'bad' mech, as you can not add endo steel or ferro fibrous, remove the jumpjets and some heatsinks, etc... BUT you can move your omnipods around, lets say you got the nova prime , 12 er medium lasers both arm stock so you got 12 energy hardpoints each arm. Well if you look at the nova D it has a ballistic in 1 arm, so you buy the nova D omnipod and put it on your prime, so now you got 6 energy and 1 ballistic and you can go with a build like 1 UAC 10, 6 small lasers. but you can also decide you want a missile hardpoint and 1 of the novas has 1 in the side torso so equip that and you got 1B, 1M, 6E, you can go with a build like 4 small lasers, 1 UAC 10, 1 SRM 6, but you also kinda want to lower your arm hardpoints for best use of quirks and stuff so you go for the nova S with 3 energy hardpoints and put 3 er mediums, 1 SRM 6, and a UAC 10 for eg...
Only place you can't change is centre torso, so if you got the nova S and get the hardpoints to get an AMS on the left and right torso that's 3 AMS.
Grasshopper is a bit fast but it is also big but JJ lets it to be agile... I need a bit more info though for what you want to suit you... However I should state in case you did not know that if you get 3 variants or alternate configeration (clan omnimechs) and get all the basic pilot skills you can get the elites for that mech which make you fire faster and move faster and so on and on. I should also mention getting all elites double your basics so you are colder, turn faster, etc...
I suggest tryign to elite your awesome or hunchback if you haven't done so. Hunchback can be a fast in your face mech but does require skill... Shadowhawk, Stormcrow, Catapult, etc may sound like mechs you may want but there is a Griffon out there with ECM that could suit you well as well as the soon for c-bills shadowcat in a few weeks... as I said, may need more info.
4. Faster projectile speed for Autocannons, Ultra utocannons, gauss, ppc, lower beam durration for lasers, higher crit chance for the weapons I listed, and I think some targeting speed related stuff, bigger the number more slots, tons, and effective it is. It isn't quite the most popular piece of the equipment but some use it.
