Don’t get me worng i love that they are difficult (even if i didnt even play the most difficult ones yet) What i dont like is the fact that require serious time to complete them but not just because they are difficult (witch is ok) but you also WASTE lot of time creating a party (seriouly why they didnt implement a frakking lfg general chat???) and also you waste a lot of time killing trash mobs because they have lots lots of hp.
What I would do?
FIRST: you really need to but some sort of LFG tool in action. I’d really like a dungeon finder extra-server, but i understand it might get complicated to implement. But at least you could put in a LFG general chat with not effort at all.
SECOND: Reduce the time spent in dungeons not by decreasing the overall difficulty, simply cut back the “menial tasks” like killing thrash mobs, or reduce the hp on bosses (witch dont make the fight easyer…just quicker)
