Both could simply be a bar. At the very least Tiger Power should be tracked via a bar, Power Guard could be tracked some other way or not tracked at all.
Could be identical to rogue's combo points (except the same teal color as monks?) and 1 point = 3 stacks. Then 5 "points" would mean a 15 stack of Brew.
Could be tracked the same way Rogue's Bandit's Guile is tracked. A single bar which can be colored Green, Yellow or Red (representing their respective buffs). Then, similar to Vengeance, the actual value of the stagger could be displayed as a number at the bottom of the bars.
Currently I have this being tracked by the former deadly poison (deadly poison no longer has stacks) tracking display. I simply changed the debuff to a buff, and changed the spell ID from Deadly Poison to Anticipation. This causes Anticipation stacks to display as green counters underneath the standard Combo Point tracker.
