there are a few general rules of thumb when building a mech. mainly try to focus on one or two weapon systems. so if a mech has say all 3 look at the quirks and see what ones the mech seems to focus more on and work from there.
for example the Orion-V (UAC jam chance 20%, UAC jam Duration 25%, IS UAC Heat gen 10%, Ballistic Cooldown 15%, Ballistic Velocity 15%, energy Cooldown 20%, Missile cooldown 15%, heat 10% with some armor buffs added in)
now looking at this the mech is Heavily Quirked towards UACs and other Ballistics to lesser degree. so looking at this in combination with its hardpoints (2 Balsitcs, 2 energy, 3 missile, 1 AMS) a UAC/20 would be a good starting point with a pair of energy weapons or even SRMs. UAC/10 with MRMs sync up well given their close range brackets though keep in mind using two different ammo dependent weapons will cut how much ammo you can take for each.
choosing all weapons in the same range bracket can be a good rule but not a hard one. also try to keep your weapon groups manageable. 2 is what you want to shoot for with perhaps a hird set up to chain fire if you are boating a weapon system (so if you are running something with a lot of SRM and a couple lasers then having a second fire Group with the SRMs on chain fire will help you keep your heat manageable without damaging yourself (in the case of override) or risking a shut down.)
another good tip is to front load your armor. the amount differs from mech to mech and from person to person. i like a little more than most but many stock mechs have WAY to much rear armor. i would say 9 pts for lights, 10 for Medium/heavies, and 11-12 for Assaults would be the max. (the more "elite" players will tell you to strip it down to just a couple points but i find this hurts your survivability if some light can one shot you from behind or an ally might not be paying attention to their outer weapons and get you in the back with an AC/10 (that or you are stupid and step in front of RACs while they are shooting.))
if you are uncertain of your abilities i would stay away from IS XLs and just stick to LEs.
also use the testing grounds often as you work on your builds. select a hotter map (i use Terra Therma) and test fire you weapons to test your heat management. that way you can add or remove heat sinks as needed. (i try to shoot for 1.40 heat management before things like L-AMS or JJs but this isn't a hard rule as some weapons like RACs just run differently.)
