For anyone new to game, I'm dead set against em. It's hard enough to learn the xbar full of skills for AST, MCH, and DRK when you start at 30 and some folks are damn clueless at 50 & 60 even though they had to level the usual way as is. For those that already are at 60 and just want to level an alt class? ... hm, nah I'm still against em. xD
I actually run a large LS specifically for leveling alts and alt classes, so this is a matter I've had to consider making an official policy on. (Full disclosure: I love leveling, it's why I have the LS. I have 3 characters at the end of HW, 3 more in 2.1, and one more I just started out. And each have multiple leveled classes.) That being said, the msq could definitely use some streamlining already.
All those fetch quests and especially the *insert a lot of rude words here* "oh you meant the EARTH crystal" quests around level 40ish can go. It doesn't help that quests give half the exp of a single at-level fate too....
