I've played a lot of mmos over the years but this is the first one where groups would spam the first two bosses of a dungeon because it was faster than just jumping in the queue and doing things that way to get their ilvl up. I've never seen anything like this - and it's not the players who are at fault for finding the most efficient way to earn tokens, it's SE's fault for not designing a system that rewards completion in the random queue.

SE has a lot to learn about dungeoning. I feel badly for everyone who is suffering as a result of really poor design. It's not going to go away until this level of token is obsoleted - I know they tried with Tam Tara which comes a little closer to the ideal of at least following a dungeon through to completion, but it doesn't end the player's desire to cherry pick dungeons because the time\reward investment is so skewed across the board.

Things like this need to be taken into account when they design dungeons.
