For some general good DPS options in mech I’ll list here:
4-cep - Generally good dps with weapon, don’t use his skills
Beck - High dps with weapon, her grenade can do massive damage (consider rooting the bounty)
Kurtz - If you can execute it gives a massive damage boost
Dogface - Use his silver skill first, get down to 1 bullet then use his bronze skill and it give you a full clip again to use
Ryker - Both skills do good damage if upgraded enough, his weapon dps is also pretty good
Kuno - Very high weapon damage, use her silver to do even faster dps and her bronze stuns doing huge damage
Harscope - If he is platinum he does great headshot damage, use his BFG to do big damage as well
Clyde - High weapon dps, use his silver first to stun this guarantees his bronze hits 100% of the time
Hideo - Slow firing but huge weapon damage, don’t use his skills
Bolt - High weapon damage and silver does damage over time, his bronze does massive damage
Panzer - High weapon damage, her bronze does huge damage, don’t use her silver
Jarek - Does decent damage with skills, nothing amazing though but can lift and stun
Shivs - Huge weapon dps, don’t use her skills
