It's a very boring affix we will be stuck with for a LONG time. It boils down to get haste buff and carry on. So far there's not a lot of pull variance from current routes, you actually clean up DoS pathing some and that's about it. I haven't found a good use for taking the stealth buff yet where it wouldn't be better to just bring a pot/rogue instead.
I didnt had the time to test the new seasonaffixe alot, but for me it sounds very interesting.The new affixe grants a huge powerincrease in M+ and extremly strong buffs in certain pulls. The routes and pulls probably change alot to play around the affixe which gonna be fun to learn and practice. Also the new affixe brings additional adds into singletarget fights for what multiple classes profit to build up ressources faster and push their singletarget dmg onto prio targets.
