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:
Lowered exp required to unlock talent points, you should be getting 6 points now after your first clear!
Crusader now starts with Whirlwind by default
Disc now starts with Retribution by default
Slightly buffed Whirlwind - increased radius by 20% and damage by 10
Let me know if this streamlines the progression!
