Wow this thread is full of wine. I'm talking cheap wine that comes in a box.
Ki is meant to be a limited resource. I watch monks now go up to a olitary mob and stun tod and spam as many ki strikes as they can and come out with more than they left with. This was never meant to be the way it worked.
Fighters and rogues don't spend haste boosts for every meaningless fight. Pallys dont spend their entire compliment of smites on a solitary single epic tiefling ranger.
I've been playing around with savants on lammania and when I have a single mob do I spam all my highest dps spells use my tier 3 ability on it and then maybe enervate/finger it if my dps only brought it to 10%? No I use sla's to bring it down but the example here is very similar to what monks do on live now except without any penalty.
Use those easy trivial fights to build up ki for the large groups or harder mobs where you'll want to spend more ki.
Let's take chrono for instance. Fight starts with a large group of mobs but that's ok you start with a pretty large compliment of ki to start a fight. Spend some to take out casters and probably the devil but after that use the rest of the straggling mobs to build up towards the next fight. Monks gain a lot over fighter splashes here in their ability to carry more ki from one fight to the next.
Is it gonna take some readjusting to play style? Sure a little but not spending the ki on trivial fights is not something hard to learn. In the end monks will be just as strong as they are now (in some ways stronger due to helplessness not affecting them as much dps wise.)
