Influence of Upgrades are to big?

[Frechheit]

I got a friend who is very good at exploder. Once he reaches "critical mass" (enough damage to blow everyone in team, or most of the team), he spends his money in things that do not raise is bounty, such as factories and creep upgrades. In endgames usually or or two kills (or even better, multiple kills) mean an upgrade or two on the spot.

Violent yet incredibly effective.

Exploder sucks. Just make Teleport breaker and he is nerfed. Moreover Exploder doesnt need skills. Everyone who can play average Bt is a good exploder when the enemies are bad.
