Well if you go into necro solo and look at those with asian clan tags that cleared 110+ with skeletons for extra CDR and obsidian ring. I am willing to put money on you can ban those. The build is unplayable without D3helper or worse... and the 117 clear guy that was no1 had for weeks had so shitty gear/para that it would have been a joke for top200. (think he is no3 EU season now, but you can notice for yourself by inspecting, also notice lack of played hours)
I do know that some players burn 1000 keys to get solo top 20, but this guy burned some yens on his bot subscription..
I do think Blizz need to start new banwaves, ASAP.
If nothing else let them all buy new accounts, Blizz wins, and the honest players wins...and who cares about the botters and their emotions, apparently they dont play the game at all, but pay some software to do most the playing. Never understood the concept.
Necro relies heavy on CDR timing, both zdps and trag and pesti, so scripting and perfect casting of multiple spell does warrant results that are unachievable for even best humans. After all we do live in an age where AI beat both best chess players and also humans in poker, so do think its more than "likely". Proof is more or less on the bots forums, not going to link those and promote anything, but they are bragging a lot.
