I have had a level 50 MNK (My main and first level 50!) for a couple weeks. I have my relic weapon, soon to be Zenith. Basically I am getting to the true end game content where skills and equipment matter.

My question is: Are there any "must have" skills from other classes that would compliment a monk?

I have started leveling CNJ just to pass some time while waiting for DF, but perhaps there is another class I should be focusing on?

Thanks for any input!
