Do you seriously want to see me stay at base and spam spikes over the entire field.
Yes. Yes I do. I also want to extend your shield range so you can still shield me. And since you'll be standing at the mana crystal anyway, it would be quite nice if the cooldowns on your skills were reduced to allow a statisfactory amount of spamming.
An odd side effect of making ground spikes cover the entire arena ( I tried this quite some time ago ), was that it became 0 cooldown and 0 mana. So, it was beyond spammable. Could take down a citadel in about 1 min, and demis would die inside the crystal.
Never did find the cause of this bug, or its solution...though I didnt spend a lot of time on it either.
