80 damage on main gun + ability, remove crit from ability and reduce cost slightly = M8 performs consistently against infantry and light vehicles and doesn't RNG squad wipe.
FYI, 80 damage is the same as the Stuart, which uses the same gun IRL.
That would balance the M8. No problem.
Well, T-70 also deals 40 dmg, yet one shots infantry if hit, so it would be enough to either increase rof or decrease scatter.
Improving damage on the other hand would make it effective against light armor, which only makes sense considering its 37mm gun of stuart.
I would love this thing to perform consistently instead of being "use ability, park in your base for the cooldown" unit, because with its current gun and MG performance, its T1 sturmtiger and nothing more.
