10 years experience means nothing in a dungeon you aren't familiar with. practice in learning/clear party's. Memorize all the steps watch some videos if needed. When you can reach to 15% in EX primal fight or have the fight memorized with no problems ask a farm group. Ask the leader and tell them your situation. Its how Ive cleared Ravan EX, Throdan EX and Sephirot EX all without messing up. The groups were understanding after I explained it to them that Ive got the fight memorized perfectly and some of them were fine with it because that's how they get their clears. I told them I can do it and proved it. Ive created farm parties myself I never put "no bonus" in PF. There are some really good players that cant clear EX fights because of other people and some people that have cleared still suck yet they join farm parties and cant carry their own weight.
