That's the case sometimes but not always. Other times maybe someone already cleared it and was in a farm mode and not progression mode. I've cleared Tsuku EX over 60 times between my 2 toons but if I'm just trying to get my Trials roulette done, I'm probably not going to be as patient compared to if I willingly went into a practice or clear PF party. I just want to get my roulette done and farm some gil/tombstones and not do 4-5 pulls wiping due to newer player(s) or bad player(s) messing up mechanics. If you are new to this fight or still need practice, you can always form a PF party and recruit ppl to learn the fight with you or you can ask friends or FC members to help. Also, I don't insult anyone or say anything mean when they mess up, I usually just wish them luck and leave or log out. I don't think that's a bad thing to do on my part.
