Bad mech. Better mech. Specifically: - Command Console does nothing at all, just a waste of tons and slots. - You've got an LRM5 which will just be eaten by AMS. - You've got an XL engine on an Atlas - don't do that. - You've got CASE (which does nothing for an XL engine) - You've got a Flamer instead of an MLas for some reason. This mech has none of those. LRM10 for range, ammo in reasonable places, a bit less leg and arm armor (which really doesn't matter all that much - no one legs an Atlas). What you lose in heat efficiency you gain back in survivability.
I agree with Dwergi. If you really wanted a troll build, there are plenty to make your's seem like cheese. 2-5
