Anyone know the best way to take down a controller:
1. Go straight for the controller and ignore the towers.
2. Just clear enough towers so that you are relatively free of interference while you pound on the controller.
3. Clear towers until XX remain, before attacking controller (define XX).
4. Clear all towers and then go for controller.
5. None of the above (because...)
From what I understand, #4 is generally the best strategy because each tower either a) adds more health to the controller than it has on its own and/or b) lends too many advantages/firepower to defenders to make a controller attack viable until it's gone.
Obviously, each situation is different, but I was hoping for generalities here...
