Personal spoil chest would be a great substitute.
Remove the whole book token system and switch to a non convoluted single token system. 1st turn = 1 tokens
2nd turn = 2 tokens
3rd turn = 3 tokens
4th turn = 4 tokens
What the rush is? Many possible reasons.
Personally? I enjoy seeing my progress with rewards. If you’re a healer or tank in a static. Good luck seeing anything for 3-4 weeks.
If you PF. Good luck in general. Week 8 or 9 now? Currently I’ve won 1 accessory for p5s and 1 leg token from p7s.
Granted luck definitely plays a big roll.
