As Mathikk said, no CR really works for Monk as you need to position yourself. As there is no indication of what the next skill is until you learn the routine off by heart, your positionals will suffer.
To be honest, if there was visual prompts in Ultima or something similar with a timer so you know how long you have to get in to position, that would be great. I.E, First spell to be used will be Dragon Kick, so Flank appears on the screen red, next is Twin Snakes so it remains Flank but gives you a time until the skill is used, then lastly it should be Rear, so it pops up rear in red with a timer. I honestly think this would be better than no indication at all, tbh. Granted, this timer will only be for Global CD which is like 2 seconds or 1.5 seconds?
