It's good that R* have nerfed tanks considering how op they were. Now they just need to nerf the lazer jet as well. The jet is stupidly op considering you could take down a tank with 3 cannon passes. That was before the tanks were nerfed as well.
lazer can be OP but they're not really a problem
the problem with tanks is that any noob (well richass lvl 70 noob XD) can order one at any time
and even you destroy it, he can just get a new one
not so with the lazer jet, takes a longass time going across the map each time to get one
and it also requires a lot more skill.
tank griefing happens pretty much every other game
the times I succesfully got griefed by a lazer can be counted on one hand really.
