Eve of the Apocalypse: Twilight

It seems to me that whenever one team spams druids (the elf special tower) that the game soon lags out. Now I'm not sure if this is because their like a 3 in 1 tower (though murlocs in gloom don't seem to cause this problem) or if they cause excess memory leaks for some reason.

They soon lagged a game on Kedge to all hell, only two lanes

I can imagine treants dont get reused, thus increasing the amount of units created by a multiple.

Wouldn't be that hard to trigger a summon Treants spell either ; )
