All right, I haven't gotten to everything yet, but I just pushed a new version with a lot of improvements.
I've reordered things as you've suggested, and I'll look into doing something more like a chart. A lot of that information does exist, but it's kind of scattered all around which isn't the best.
This is unfortunately very hard to do at the moment, because WCL has some issues keeping track of secondary resources like Chi. Take a look at this fight for example, where the graph shows the monk going to 9 chi but thinks 0 were wasted. I considered just tracking Chi gain/loss and doing it myself, but that wouldn't work unless I knew how many you started the fight with.
Kihra mentioned on the WCL forums that resource handling was scheduled to get a revamp in time for Legion, so hopefully I can use that information once it's fixed up.
Fixed this, it was a silly bug.
Makes sense, and it's probably true for a number of other abilities as well, so I added 10 seconds of leeway as default for all long cooldowns.
I added a note about this in the section's description. Or do you think it might even be better to not display this at all?
Fixed, and I also added data about the damage stored & explosions for Soul Cap and legendary ring, as a default for all specs too.
Soul Cap is a little funky because it incorrectly shows the explosion in the ability breakdown of stored damage, but it doesn't affect the total and is kind of a pain to fix, so I'll get to it later.
This is on my todo list
Thanks to both of you for the excellent feedback!
