So, if player#1 have better spec than player#2, faster mouse/keyboard, High-end build etc, which allows him to play with more fps, be faster, see further, is it pay to win for You too? Ridiculous.
According to multiboxers, I have mixed feelings here. They are annoying, from time to time, but surely not more than gankers, AH NPC killers, AH abusers (stacking 1 piece of material on AH) or bots (for example, 20 Wool Cloth is worth ~40g on horde ah for several days. Anytime new auction is set up with 20 wool cloths, its bought in no time and new auction is opened with price 40g/20 pieces. You can tell me that its just a normal guy paying attention, but if Im logging for few days, random hours, and everytime situation looks this same - lets be honest here, its bot, not player. I wonder how big part of AH is controlled by this ****).
The only situation I've really seen it as a problem is WG - I agree, everytime there are multiboxers one shotting everyone. So maybe just limit them in WG would be good enough action?
For now I'm just playing pvp, mostly BG (don't have time for more) and to be honest, for hundreds of BGs, I may seen few multiboxers.
