from what ive seen its a pretty common ban rate, if your planning on using the ess to bot rc just buy the ess, you still make plenty of money selling the nat/law runes.
i have a hp to and it heats up pretty quickly, what i do is just put something under it to where the vent isnt above anything, the more free the vent is the less it heats it and its worked pretty well for me.
if your patient enough get your rc high enough for natures and bot those, you can bring it a good amount about 300 nats a hour and its a very low ban rate.
i want it because i have first world probs... botting on all my accounts makes me not have anything to do netflix would entertain me while i bot and what not.
