Hi am a marauder lvl 31 (almost 32), i recon iv done every side quest possible and all MRD quests up to lvl30, and almost done all lvl4 MRD hunting log, all grand company log lvl1, but my story quests are only up to lvl 26 (I think)

I haven't leved any other classes and used the slots on MRD

I need to level GLD to level 15 for next MRD quest, which am guessing gives me Warrior class,

Should I stop powering forward with MRD and start GLD?

Do I even need warrior crystal, I like being a MRD?

Should I level up archer, lancer, courja for ability slots for MRD?

Help? Haha

Edit: also if I carry on with main story as MRD ill probley end up level 34 coz of the crazy amounts of exp quests give
