Some things that I believe will better the game

Hello,
I just wanted to post some things that I would like to see changed in the game. One would be the respond rate of enemies, they respond way too quickly especially around bosses that you have to fight. Two would be the armor, is it at all possible to have armor that looks different? everyone looks the same all the time because armor does not have different looks. Other than that I really love the game. It would also be fun if it had an alliance and horde faction like WOW with pvp, though I do know that this does not go or play with the games story line.
