The root of the problem lies solely in the server-side detection of avoiding an AoE. The Primal fights are not a level playing field for all players, they scale in difficulty dependent upon your location relative to the server, and how loaded your link to the server is. This, coupled with die-once/stay-dead penalties for a number of the fights, which then in turn generally causing team wipes as a result, makes a number of the instances extremely frustrating for significant portions of the playing population. For me, after looking at the extreme primal fights online, I already know that they are utterly impossible with server-side hit detection for my network latency, even with WTFast running. It is disappointing to pay for a game that sections of the content are effectively excluded from play due to technical difficulties.
