To be honest I'd rather see Tornado Kick go than stay. Perfect Balance has utility beyond Tornado Kick and should remain as is, particularly because it serves as MNK's main form of AoE burst. I want to get rid of TK mostly because I'd like One Ilm Punch to be a GL generator instead of Riddle of Wind, but that would become too good pretty fast with TK's current cooldown.
Chakra and Form Shift can fill those needs without disrupting your DPS by much either, especially considering Fists of Wind will help in those situations as well. The main reason they seem to lack a ranged attack is because they'd technically require three, but I'd probably just make a ranged attack version of Form Shift (with a GL refresh if in Coeurl as normal) if it was absolutely necessary.
Same goes for Dragoon. Make Piercing Talon extend Blood of the Dragon.
