You can't please everyone, as yoshi stated these mobs mainly A and S ranks are not meant to be solo'd so if you are out there running around solo trying to get full credit on an S rank that's your own problem. Sands and Oils problem, all Sold. gear isn't best in slot and even if you get a player to ilv110 doesn't mean they can beat the raid content. I've seen people that complain that they are at ilv100 and still can't beat twintania because it is too "hard". Also Hunting does require some skill, you still need to dodge aoe's and the A and S ranks have some annoying abilities like that stupid lizard in southern Than.

@shougun We won't be seeing an expansion for at least another 6 months we still need 2.4 to end Coil, and 2.5 to end CT series (unless they release it in 2.4 which would be awesome)

a great fix would be an hp buff to all mobs because even S ranks die within a minute
