Hi,
I got tired of guessing how I should gem with all my new Sunwell loots, so I created a little
spreadsheet to tell me. Basically, I wanted something to tell me if I should cut a parry gem or a dodge gem for a red socket that I decided I wanted to use on avoidance (or decide not to if the avoidance gains weren't worth it). I believe that I'm using the correct equations for 70, but if someone could give it a look over and ensure I'm not being stupid that would be grand.
For those curious about the results, I'm a T6/mid-Sunwell prot pally with a character sheet that reads 31% dodge and 16.5% parry without the 5 gems that I wanted to throw at avoidance. Gemming full dodge versus full parry only resulted in a .2% avoidance deficit (parry was worse). Throwing all 50 points at dodge also only resulted in a 1.76% improvement in avoidance. Prior to 3.0 that would have been 2.62%, so there is a fairly significant drop off.
