I know I'm not a Ghost Bear, but I can't help but feel as though you guys are like my future brother and sister mech pilots, and that we'll get along rather well some time far off in the future. This plus the fact that I hadn't seen any Uller (Kit Fox) builds in the thread, I thought I'd share mine.
LRMbrella Kit Fox
This is my ultimate Deathball support mech, ECM plus triple AMS (and the faster firing rate module) = LRMs be gone. Also, yes that is 11k ams ammo (and I've had matches where I've used over 10000). I play this when I want to protect that lovely assault/heavy mech in my life from all those evil LRM boats. On the downside, I tend not to do too much damage in this mech (typically 200-300) as I focus more on keeping my teammates LRM free, and there are no cbill/exp rewards for shooting down missiles with AMS...
Fire Support Kit Fox
This one trades out all the AMS, and the active probe for an ERPPC and a couple extra heat sinks. A more offensive build than the LRMbrella, this Kit Fox can dish out some pain at all ranges, has some machine guns to help finish off weakened enemies at close range, and ECM to help out the team/be sneaky. While I don't put out as much damage as you guys in your heavier clan mechs, with this setup I can often put up 500 to 600 damage with a couple kills (which IMO isn't too bad for a light mech who also helps the team with ECM coverage.) and occasionally even more.
