Exploitable bug to permanently increase brawler attack speed

[Dharilos]

So there's an exploit to gain the pre-nerf unarmed attack speeds of 125% and 166.7% for heavy and light gloves.

Here are the steps to replicate it:
1) Enable "Auto-assign talent points at birth" in Options > Game Options > Gameplay (It's on by default)
2) Create a brawler of any race
3) Take a point out of unarmed mastery immediately at birth, then close out of the level-up window
4) Open the level-up window again, then assign a point into unarmed mastery
5) If you check the character sheet at this point, it should display attack speeds of 125% for heavy gloves and 166.7% for light gloves
