I don't want to come and ruin your parade, but I did Garuda (HM) with level 40 gear. and it was me that kept the morale up and people alive, the other healer did close to nothing.
Just because someone doesn't have Darklight or Strategos doesn't mean they're going to suck, as of now I have a level 40 belt simply because I'm trying for the Strategos belt. Don't get me wrong I understand how this can make you feel "Oh this guy hasn't got the exact same gear as me" He may also have quicker reflexes and has a little more skill to make up for his gear. Not everyone is lucky, I did Ifrit 36 times just for the cane. Never failed unless someone cried that my gear was lackluster and left.
It was the same with Garuda and it'll be the same with Titan. I'm there for some better gear, not to ruin your run or whatever. -- I'm going to try as hard as I can.
