While I do agree that it is difficult to get people to help with clears, I found a better approach is to just be that person. I'll usually word the party finder like "Clear for 1 / learn if you want / help if you want" and I got a surprising amount of people willing to help and every party ended the lockout with a clear.
Since launch, I think I've led and helped at least 5-6 FC members and friends get their Titania/Innocence clears, as well as their equipment and weapons. Helping them out was motivating enough to not even consider it a grind. Cut to 2 days ago, I'm sitting on 50 Titania totems and I happened to roll an 86 on the mount and succeed. As rewarding as it felt, the fact I got someone who never did current extremes to try Titania on a saturday and get their weapon the next day was a reward in and of itself.
