No wonder we don't have nice things when all you people do is complain about every little issue.

First, it's not an exploit until SE says it is. Untill then, it's an alternative strategy.

Second, SE has more important things to to than to worry about players using a piece of terrain to beat one boss on one dungeon that drops sub-optimal gear and weekly restricted currency on the last boss.

Third, if your party wants to use this strategy and you don't, then leave the party. You have free will. Nobody is forcing you to do anything.

Fourth, if you are frustrated that this happens in duty finder, make some friends or join an FC and create your own AK group. Take some ownership over the situation and do something instead of complaining about it on the forums.

The sense of entitlement and egocentric thought in parts of this community is astounding.
