'Mech loadouts are like pairs of shoes. The Meta acts as a one size fits all design but to some that might a few numbers too small, too large, or they just happen to not like the way they fit their feet.
This thread is to share all those build specifications you came up with to fit you and your intended play style best. There are a lot of one of a kind designs to explore and share and I would like this thread to stay fairly clear of Meta builds. We all know they work well, that's why they are the Meta, so let's celebrate the roads less traveled, shall we?

Things I'd like to know:
- 'Mech Chassis and Variant
- Weapons configuration
- Engine rating and upgrades (optional, but appreciated)
- Smurfy link (optional)
- Intended role (Brawler/Striker/Skirmisher/etc.)
- Weapon groups with short explanation (optional)
- A summary of the 'Mechs play style, combat behavior and weapon usage. Explain why the 'Mech fits you and how you can make it work best.
I'll of course go ahead and start with an example of my own and my current favorite 'Mech.
STK-M Misery
Current paint job:

I was too lazy to crop the image to hide the UI. Oh well...
1x LB 10-X AC
1x SRM6
1x PPC
4x Medium Laser
STD 300 Engine, Endo Steel Structure, Artemis IV, 16 Double Heat Sinks (12 Internal, 4 external)
Smurfy link
Intended Role: Brawler/Front Line Support
Weapon Groups:
Group 1: LB 10-X AC + SRM6, Chain fire
Group 2: 4x Medium Laser, Chain fire
Group 3: PPC
Group 4: PPC + LB 10-X AC
The reason I chain fire my LB and SRM6 is to prevent them from firing simultaneously at any time. The offset of the weapons makes twisting away difficult and will cause substantial damage over time spread over the entire torso area with the CT being in the main focus due to the narrow spread. The Medium lasers are being chain fired for a similar reason. 4 MLs chain fired will generate continuous damage, similar to MGs, but without the need of ammunition at the trade-off of generating solid 4 heat per second in return. On most maps, using only the LB and SRM6 will be cool enough to continuously fire them until the 'Mech has cooled down enough to use its secondary weapons again.
The PPC makes up for the lack of long-range firepower and replaced the CT-mounted Large Pulse Laser of the previous iteration of the design and is the only source of instantaneous pinpoint damage in this build. It is perfect for cracking large pieces of armor to weaken potential targets before engaging them with the two primary groups. Group 4 is for targets at 600-700m range, making use of the high range and speed of the two weapons, group 3 is for anything beyond that range or when needed to deliver a short range pinpoint blast to an enemy.
This design has proven to be a vicious brawler due to its ability to keep an enemy occupied with continuous damage over a long period of time (according to Weapons lab, without the PPC, the 'Mech has a heat efficiency of 56% and can fire for up to 27 seconds (23 with basics only) without overheating). Its killing potential doesn't come from using large weaponry but in very high staying power it demonstrates by being hard to kill, pouring out consistent damage and keeping enemy attention firmly focused on itself which allows its teammates to move up from behind it to take out any opposition. While it is somewhat lacking in single fights, it can perform extremely well in a group effort by taking the lead and focusing fire on itself while providing suppressive fire.
One of the tasks this build also excels at is choke point dominance. When enemies try to force themselves through a choke point, the Misery can immediately punish the individual 'Mechs with constant damage as they try to step out, draining them of momentum and potentially force them to retreat, blocking the choke point for their teammates. It can also do some harassing to discourage pushes through the choke point, but since it lacks high instantaneous damage, this tactic should be used with some moderation and not as a primary means of attacking.
Why is this build perfect for me?
I'm someone that likes taking the initiative and I prefer acting in a supportive role rather than taking the direct offense, but I'm also quite straight-forward. This build combines the aggressive play style of a spearhead 'Mech with the abilities of a front line fire-supporter. It is quite simple-minded but what it can do, it can do surprisingly well.
Now I'd like you to share you own unique configurations. Don't worry, there are no "bad" builds here. We're all crazy people after all

Happy posting.
