I've played both tanks at 50 and think both are fun on different situations. I'm fine with tanking as long as I've done the dungeon/run 5+ times before. First time is always messy and possibly a wipe fest when I'm trying to figure out what to pull, where to pull, which way to make the mobs face etc. Darkhold and Wanderer's Palace were nightmares to me on first tries and I was ready to give up tanking, but my healer friend kept encouraging me and my tank friend gave me tips and I managed to pull through. I haven't tanked Coil or Extremes, and I don't plan to, as I leveled both tanks only to help my friends to level their classes through dungeons.

Going back to my scholar which is my main, is so relaxing. Can live happily in a bubble of ignorance and bliss. I didn't learn Crystal Tower tactics before I actually took my monk there even though I had done CT ~50 times on scholar before that. Though... Twintania is giving me grey hair as a scholar. x'D
