Healing elixirs is already pretty good (and in case you missed it, it's getting buffed in 5.4: Healing Elixirs will no longer activate if the Monk is already at full health, and activate automatically when the Monk has less than 35% of their maximum health.)
But I agree that we have very few talent choices. Having some tiers being clearly the best in 95%+ of situations is fine as long as it isn't more than a few. What makes it worse is that our T90 talents are all pretty bad, xuen included (he would be quite a bit better if he didn't break cc, but even then he'd be kind of lackluster at 45 sec duration, maybe cut it to 20-25 sec duration and double his dmg or something).
It does seem like blizz is slowly chipping away at "fixing" the talents though. At least now ring of peace will have some situational uses vs some wizcleaves for example. Still kind of wish they removed it from silence/disarm DRs to make it slightly more attractive/less punishing to use since it procs 2 DRs atm.
The disarm portion of RoP is utterly worthless with weapon chains. They sometimes don't even miss a global.
