What did we have so far?
One Bolstering week - you need to kite when mobs get highly buffed - only a few seconds if your group is good, way longer is your group is not so good...
One Necrotic week - The Kiting Week(TM)
One Sanguine week - Here you want to kite for other reasons than defense, mostly because you don't want melee mobs to die next to ranged mobs
One raging week - The Kiting Week Reloaded(TM)
So yeah, we trained our running skills a lot. Add also a lack of gear on top of that as it's first season...
Tanking is always tricky on 1st seasons, an issue in this game Blizzard was not able to solve yet. But TBH tanking is in a way better state than in BFA S1, which was a total tanking nightmare.
