I personally hope they do away with the GL ramp up into gaining 3/4 GL. With the changes made to Form Shift and Perfect Balance I hope to see something like a hybrid of warrior/nin gameplay.
Currently:Form Shift just changes your form and resets the timer....that's it. We may see something akin to huton/Storm Eye instead. Finishing a combo starts/resets it(like armor crush), using form shift resets it.
Currently: Perfect Balance is essentially Inner Release on 90 sec CD for a burst phase that only works with form combos. I do find myself using this almost every trash pack to spam Rockbreaker + ROF + Brotherhood. Very powerful and constantly edge close to pulling hate off the tank if they aren't AOEing enough. Outside of my initial opener for GL gains, this is my new Inner Release.
Future: Personally, GL in it's current form is gone and change to something like Beast Gauge...(I hope) The GL per stack buff turned into a straight static buff that we have at all times without the punishing side affects of losing it. Essentially 1-80 we get a steady increase to speed/potency passively. The new "GL gauge" builds up by finishing combos with a max 100 points. Perfect Balance and TK would use 50 each. This would offer so much choice(personally) and open the job up to so many strategies. Do I wanna unload Perfect Balance for crazy AOE? or drop 2 tornado kicks?
Also this prevents spamming Perfect Balance as you need to FINISH a combo to gain GL resources. I have thought this through a lot.
Future: Chackra is "fine" since I use it quite a lot, but the RNG blows. Currently use SSS > Forbidden > Elixir Field/Shoulder tackle. I think SSS should be turned into a chackra gain skill with a small cooldown timer and made into a oGCD, and remove the slow down effect. This would be something I can weave to help supplement my chackra gains. If the RNG is so bad just pop SSS. (Kind of like Sleeve Draw)
Future: That leaves TK and this is where I feel something akin to beast gauge or nenki would shine. Building up to a double tornado kick + riddle of fire! Sounds...awesome honestly! How we gain these would be dependent on doing our combos effectively and using perfect balance won't work as you need to finish your combos.
Future: And lastly...stances. Fists of Wind +5% Crit Buff, Fists of Fire +5% damage Buff, Fist of Earth +5% reduced damage. Stances has always been a sore subject all the way back to ARR...they just always took a back seat until Stormblood offered the whole riddle mess, and then was undone.
No matter how you look at it...Monk really does need a complete rework.
