i mean challenge no longer give much exp.. and the only reason people would farm these is for gear.. i have tried team up with other player, but these challenge are not so easy to learn, most of the time it end badly.. especially the mansion series. please consider boost the challenge reward, so people would actually go there farm stuff.
p.s. it is really really hard to find a group to do challenge.. the gear aren't much good...perhaps make them more newbie friendly? so people new to the game would actually consider getting this pack for those easy acquire gears.
