Something really needs to be done about Zzrot Portal
The problem was never its HP, the problem is that it pushes way too fucking fast. Towers are so weak that a single wave + a few Zzrot bugs is enough to take them down all on their own. Nerf the range of the bugs, or nerf the damage they do to towers. At the very least let people get gold by killing the damn things. Better yet, BUFF TOWERS.
