you brought up very valid points which made me re-think some new stuff :

2- I think then adding 10 sec buff after purify that gives you 100% resist sleep, stun, CC might be the valid method. this essentially remove the abuse of applying CC just after purify immediately.

7- I think if they add up a system where you get lower wolf marks the more times you kill the same player in wolves den might fix the abuse. also I did mention it needs to be looked carefully so the board doesn't become meaningless , I wish i have prefect solution but it is imo important to have. especially for people who already got the gear, at least they get another objective to be in the board etc. on top of that receiving special title whenever they are top 10 , top 100 etc.

last on number 1, I think in short term fight you are right, but if the fight drags on, it gets annoying not to have TP after i use all TP regen moves, keep the chase over and over for classes that have same CD as sprint as melees yet they dont use TP imo needs to be fixed.
