I have this mech with CW in mind where I have found speed to be really important. It has a nice laser punch but also has a cool firing consistent damaging dual ac5 weapon system.
You want to use this build for CW, you want this mech to last 9 tons of AC5 ammo, yet you give it XL... Here is a STD version. A bit less armor/ammo (but those requction are from shield arm, much better than an arm chucked full of ammo with no CASE next to an XL engine), a bit less DHS and slower (usually the case for going STD). But otherwise it is quite good for the CW type game. You have STD to last longer. See how it goes.
That might work if I wasnt so stubborn. If I was willing to compromise on the speed I think I'd bring a different mech or an entirely different build. Right now speed is what makes this mech somewhat unique for me.
