Demo Update - Shield Starting Abilities, Gain Talents Faster

Hi Tanks!

Watching you play the demo I realize it was taking a bit too long to unlock those tier 2 talents preciously needed to pass tanking 201.

I also saw some frustration when the offensive ability (whirlwind/retribution) wasn't in the cards for the first few levels, so:

1. Lowered exp required to unlock talent points, you should be getting 6 points now after your first clear!

2. Crusader now starts with Whirlwind by default

3. Disc now starts with Retribution by default

4. Slightly buffed Whirlwind - increased radius by 20% and damage by 10

Let me know if this streamlines the progression!
