The fact that you dont think its ridiculous the level of complexity the planing and the sometimes precognitive ability you'll be required to have to pull off what your casually spouting off as "your just bad" because its something hunters are not interested in doing.
Boss timer mods take the guess work out of preplanning. Most of the time if a boss is going to perform a move that's going to require you to move, there's a timer associated with that move.
Also having fox delegated to pvp only is not something to be happy about considering the pathetic state of hunter pvp.
Hunters are in an extremely sad state in PvP. So sad that I truly believe that Hunters are broken in PvP. But having Fox relegated to a "PvP only" aspect may not be such a bad idea. Blizzard could tweak Fox in a way that would make it so that it would be the default aspect to use in PvP. Aspect twisting isn't good in PvE and it's not good in PvP.
