(edited to fit everything)
Tornado Kick-No one wants to lose all their stacks for an off-GCD.Either remove the loss of stacks entirely,or only have it cost 1 stack.Alternatively, it can add a damage buff on execution,so that even when losing all stacks of GL,you would at least have something to fill in the gap.
Stances-I actually really like how Dragon Kick buffs your next Bootshine,and I think Twin Snakes and Demolish should do the same thing for True Strike and Snap Punch, respectively.Twin snakes can add an effect ( like, "iron fist") making your next True Strike deal double damage and also open a Chakra,and Demolish could add an effect that makes your next Snap Punch also do double damage and reduce all your off-GCD's by 1 second (these are just examples).
Fists of Fire/Wind/Earth-These are all pretty lame.Instead,lets make switching between them mandatory and provide better, temporary effects.Fists of Fire could replace Riddle of Fire,dramatically increasing damage output but slowing down weaponskills, which would be the window to use any off-GCD's.Fists of Wind should do the opposite, dramatically increasing skill speed (something like Machinists old Rapid Fire) and also adding addition potency with every attack (similar to Paladin's old Sword Oath) and add a cool visual similar to Ninja's Bunshin.It should be worked in so that you flow between both stances.Get rid of Fists of Earth completely,and instead give Monk a new ability for reducing damage temporarily,like reworking Riddle of Earth as follows:
Riddle of Earth:Monk stands still and channels,reducing all damage taken by a large percentage.At the end of the effect,heal for 100 potency for every attack sustained while channeling.This is way cooler and provides a better mechanic then what Fists of Earth and Riddle of Earth originally intended.
More Off-GCD's.We lost a lot of off-GCD's in Shadowbringers,so low level dungeons feel especially boring.We should bring back all the off-GCD's we lost so we have more to do during what is currently our Riddle of Fire.
Perfect Balance:Just make it give us max stacks on use,or bring back Internal Release and make it give us max stacks on use.Monks struggle in dungeons to keep stacks up and it's a real pain.Also, the duration of stances needs to be increased to better match the duration of Greased Lightning.Too many times I'll still have time before losing GL stacks, but the stance duration runs out and I lose Coeurl form before I can attack.
Form shift should just go.Either that or change it into an off-GCD ability that opens up all stances for your next weapon skill,like a miniature Perfect Balance.This would be great if we also changed Perfect Balance to just give us max stacks instead.
These are just a few things I thought of off the top of my head,and I feel like Monk would be a lot more fun with these implemented,or something similar.
That's my thoughts on Monk! Thanks for reading!
