For playing in regular ol' pub games.
Any mech that you don't fly a lot. Repair kit mk3 Extractor mk2 fuel converter 1
Any mech that you fly a lot. Air compressor, repair kit, extractor mk1
Items: Emp Mk2 Orb Mk2
These internal/item setups nearly insure success for anyone who can pilot their mech without getting into suicidal situations. Specifically in missile assault, tdm, coop, and dm modes were health orbs are dropped on mech deaths.
Mechs themselves are pretty well balanced these days. Just play to the strengths (speed/hp/weapons).
There are a lot of players that will frown upon you for running repair kit + extractor. But it really doesn't matter unless you plan on playing in competitive community events or joining TDM. In which that sort of internal setup is not allowed due to being a dominant strategy.
As far as siege meta goes.
Same items as above.
Internals are largely personal preference of deflectors, armor fusor, fuel converter, and/or air compressor internals.
And if you want to be a god among pilots use the Axe-Attack meta. Run blockade mk2 on your burst mechs and play real flashy like.
Welcome back to the game dude! Add me in game and check out some of the community events!
