I usualy run exs with my scholar because I wasn't sure (until yesterday) if I could handle pulls with my PLD. Since my healer is my main, I do appreciate when a tank uses his cooldowns, so when I play my PLD, I do the same.
Even if I SR HL roulette, and now ex, I wouldn't mind pulling less. I've run into a fair numbers of tanks who were doing small pulls. A lot more than what I was expecting when I was looking for advices on forums and was reading posts from badass tanks who were pulling 35425 dungeons at the same time. In game tanks =/= forum tanks.
It's really intimidating to play a lvl 50 tank for the first time. I wish I'd never read forums first and just enjoy doing dungeons. It took me a very long time just to start doing EX roulette with my PLD because of this mentality ( and I didn't have any trouble doing big pulls or keeping hate. I was just... scared of others reaction).
Now, with 2.5 I'll do all the new dungeons with my PLD. No pressure. It's good for once.
