Sadly I only have level 14 HQ, so I can't farm epic items (but I'm close of farming upgrade kits, wich I think its better than common items). By the way I'm also thinking about getting rid of heat bomb and changing the rocket launcher temporarily for a frantic brute, bc of the high damage. But I'm not sure tho, and I don't have one lol.
Well, the thing is done. I did the change, and I think it works. I'll use the lightning platinum vest for my next mech, wich will be an electric tipe lol
