I feel that with so many ways to bypass positionals as a MNK, they became more pointless than ever, just like Greased Lightning... Honestly, I don't thinnk positionals is a bad concept, but I think they feel weird to play with the responsiveness of XIV's combat system.
Surprisingly, everything I wished for MNK (no GL, less/no positionals, Sabin blitz inspiration) is happening - I'm really excited to try it, I may shelf NIN as my melee dps job.
