46k Mind Blasts / 92k Mind Blast Criticals on PTR :D

The 21,6% it most likely just a tooltip error. 21,6% extra damage per orb is just absurd, and that's why the MB hit for way too much on the ptr. On live it works correctly, giving only the 8*1,25% =10% per orb as baseline.

Who says that it did ever work correctly on live? For me at least it never did. It is very similar to Balance Druids Eclipse, that's why i always thought it wasn't working correctly on live realms.

It was learned at Level 10, had a 0% damage boost on the tooltip, but it provided a 10% damage boost. This was kind of dumb.
At leven 80 you obtained your mastery, which should increase the effect of Shadow Orbs by 10%. So you had two possibilities.
Either it would be the 0% tooltip + 10%, or the 10% damage boost + 10%. It was the first one, and that was dumb.

Now it works like exactly like Balance Druids Eclipse. It has a 10% baseline damage boost, and mastery is added on that damage boost for a total of 21.6%.
How it worked on live realms was wrong. The permanent bugged at 20% tooltip we still have on live shows that. But just to few people ever think beyond that.
