In case you haven’t checked, the new TankPoints is out a few days ago. It works correctly with 3.2 mechanics, but you have to edit the TOC file (to 30200) since he forgot to do that. It’s safe to edit the TOC file, and will make it load without having to enable ‘out of date addons’ in-game.
TankPoints is correctly calculating avoidance, but I do not think it fixed the Frigid Dreadplate bug I found (so DKs should add 3% miss).
TankTotals has been updated also recently with performance improvements. I’m actually using both addons now. I’ve become quite accustomed to seeing my avoidance going up and down during a fight, kinda cool for a geek like me.
