This allows casual players to get some gear, as well as allowing people that have been shafted by loot to get something. The thing is, raiders are not supposed to be motivated by gearr. People that want to raid should be motivated by challenge. Yes, this is unfavorable because of people's time and hard work spent to get that gear. Getting the second tier of gear isn't too bad though when we have 3 tiers.

Take away the carrot on the stick and you take away the reason to raid.
