Speaking of Toto-Rak if they force level sync on content like that (not end game content) they really need to bump that drop rate up. Because I only went in there once at the appropriate level. Otherwise I did a few quick runs to get the gear. I doubt anyone but serious collectors will go into a non-end game content dungeon more then once, requiring a full party, if its going to take them 10+ challenging fights to get eh gear for 10-20 levels. Its not like you can solo toto-rak at level 25, you need a full group at that level. (Or do some combination of gear+ and rate manipulations - as it stands level sync would kill the few amount of visits to toto-rak that do happen even now)
Forced level sync specially on unsoloable content is a bad idea. It took me hours to get a party to do the baby Ifrit main quest, and thats when 3 level 50s felt bad for me and came as body count (who also owned him before I finished cutscene). But I ---highly--- doubt those three would have come if they where going to get their gear tossed to shit, no reward, and had the chance of wipping over and over. Prehaps they should add "ok" npcs you can bring along incase you cant get the body count (in this way you can maintain level sync - but not be screwed into hours of LFG). I can only imagine how long it would take to get a group for Ifrit with level sync after a year or so of 2.0 out, if you dont have friends you better make some because you'd never get it done otherwise.
Just to make it clear - I'm not against level sync in a general sense; however, I am very wary of its implementation. It should only be something we look forward to not something like "oh dammit I'm going to have to sync with you...".
