Did Crystal Tower. It was as frustrating and irritating as I expected it to be. People not listening, people not explaining despite half the party being new, people leaving after the chest they want, people throwing hissy fits despite being terrible players themselves etc. The 4-hour lockout on party boots is sure nice too. All this on top of a time limit.
At most I'll do it once a week and make sure I get a drop even if it's one nobody wants (made out with a healer sash this time since my WHM just hit 50), if even that. I still can't believe SE thought this shit was a good idea. This was supposed to be the major thing of interest in this patch (along with housing) and they just had to ruin it with all kinds of idiotic decisions.
That aside, the dungeon itself is pretty cool-looking (although the layout is just bland, it's just 3 hallways, but that's MMO "dungeons" nowadays) and I'm sure I'd like the boss fights a lot more if I didn't have to deal with people.
