If 1 in 5 of those made it live, it'd make a massive difference to the class
Possibly tie certain parts to the "oaths", seeing if we can get more content introduced for us, without overpowering things by giving all of it.
One idea I very much liked the concept of is turning a DK into a 2H based tank. Move shield of fear to a parry bonus, shift retaliate to work off parry aswell. Leave vengeance where it is on block though, with a stun and a cool down, it's a little bit like an easter egg.
Many good ideas. I like it.... Like it a lot.
