I think this is something the dev should really look at.
I just joined a random tier 2 dungeon by paying the 10CE and 200C, after i join i ended up in the restless in with other 3 guys, without saying a word or do anything they just kicked me right away.
I can deal with it being kicked for no reason, since i still got my 10 CE; but i lose my 200C.
WTF dev, if i lose that 200c after sometime playing in the dungeon, fine.......but i was there only for bloody 5 secs. thats 200c gone for no god damn reason.
i think some kind of change should be added.
you pay 200 cr for going to dungeons you havent had access for
