Along the lines of HoT Tedium, I wonder if anyone can confirm what I *think* I'm seeing with SRMP. As mentioned, it is most efficient to refresh the stack of SRMP before it expires. The heal ticks once every 3 seconds for 15 seconds. You obviously want to try to get 4 ticks off before refreshing the stack for max efficiency. So let's say you refresh the stack at 14.5 seconds... well what I think I'm seeing is that the timer resets to zero, and the target will not be healed until the first tick of the new stack at 3 seconds. Now you've gone from the 12 second mark on the first set to the 3 second mark of the new set... that's 5.5 seconds the target has gone without getting health.
I think this means the most efficient time to refresh the stack is right after the 4th tick (as close to 12 seconds as possible). Talk about tedium. It's a nightmare to try to keep track of this.
Add pugnacity, Upper Hand, and energy regen and you've got absolute madness. Strangely, it IS kind of fun... you just aren't aloud to blink! Totally agree that some UI tweaks would go a long way.
