Did you want replays where Impalers are clearly overpowered? Here you go, I spammed Impalers and easily got CA. I didn't even bother cloaking them! They tried so hard to kill them - cloaked snitches, raiders, even a krow. I used Impaler's superior HP and speed to just run away.

And it's not just that. Every time anyone attempts to kill atrillery, they leave tons of reclaim for the enemy team. Even if they suceed, the reclaim from the killed arty will make the victory a hollow one. Considering all of that, Impalers are way overtuned.
