One thing we might all be dancing around is the fact that we all play monks differently. I think the biggest factor, especially with combos, is how your playstyle is set up? What are you using hardware wise to play DDO? Is it a simple keyboard and mouse? If so then I definitely can see where 16 hotbars worth of clickies are a pain! On the flip side, if you are using a more advanced set up and have certain functions macro'd, then it becomes a little easier to pay and control.
I run a light monk, always have as its just what I prefer. I don't use alot of hotbars. I have a bar set up with my basics (Stunning fist, light ki strike, elemental strikes, etc). Those are tied to my number bar on my keyboard. I then have another bar with my other strikes such as QP, jade strike, eagle claw, etc.. that is tied to the buttons on the side of my G600 mouse. The combination means I can effectively use my strikes while being able to move around.
Another note on strikes, I find that pacing is the key. I can't just bash buttons fast to try and get the strikes to work, but if I go at a pace, I am more successful... again, just my playstyle.
What I am trying to say is that the experience with the class can vary with the playstyle of the person. That is more prevalent with the monk than any other class in the game. Its partly why I love this class (well, that and punching things is so much fun). I would love to see the MRR get buffed. I think make that small tweak and the monk class is good to go.
