Reinventing the tank cannons

[k-bones]

I'm not wrong. It does 300 * 40 = 12000 damage!

Still it's strong enough. And gives the tank a free 4k weapon, why should the tank deserve a stronger weapon?

because it costs 18k. notice that other abilities also do more damage per level, so why not TC too? I say let it be not the last picked skill.
