Well i mean, for now you can be happy to try using range gun (individual guns are far cheaper then other factions join speed'n'range) and some asylums with auroras to block overcharges and remove the tank's weaknesses, if not, try bombing him into smithereens, having air control as aeon is always important
I know you're in LDB, so ask me or This_Guy if he's on to check out a replay if ya need anymore help
