So you would force others to play in a method to the liking of the masses? Just do it because everyone else does? Fall in line with us or pay? No. Everyone has the right to play the way they want, whether they want to exploit a fate for exp or complete a fate for rewards, we all play the game to have fun and each persons view of fun is different. And SE has a history of failing to address issues even severe ones, its remarkable they even addressed the AK one as fast as they did.
