Are you doing raid? If not you should. I would prioritize builds to do good in raid over builds for arena or campaign.
save clan (titan) coins for the premium pack.
save red coins for 2k premium pack deal.
can you farm big boy boss on easy? If not make this a goal.
red or blue vest are the best torsos. Use windogo, brutality or nightmare until you get vest.
I am an energy guy but personally feel heat mechs are best for campaign and raid. I use sword hammer combo to cover range 1-2 and push enemy away. Then I use the range 3-6 side blasters to over heat them. No need for top weapons.
base, keep maxing everything. Not sure the level for factory but they will have a super cheap option. Itβs best option if your gold income isnβt super high.
Oh. And donβt use mixed element builds. Weapons should all be energy or heat or physical.
And only need two weapons per range zone. So like no need for two shotguns and a sword. Or like no need for three weapons with range 3-6.
