I get that you need a combination of raids and SP events to get the materials to limit break, but whats best once you are done with that? There's a lot of other tasks available:

Farming N weapons and eidolons for enhancement (slow, assuming low priority)
Farming Raid SR weapons
Farming SR Eidolons from story quests
Farming potion trades in the Shop

I really hate the first 3, because I feel the events will get me there anyway. Is there a better use of my time?
