Its a nearly impossible task to try to balance the following three separate things:

PvP with CP
PvP without CP (BGs)
PvE

when the only difference between PvP (both with and without CP) is one Battle Spirit modifier.

I find ZOS swings wildly on balance and tends to break different content with each attempt to fix a problem they created in one of these three.

Tank 'meta' was never a real thing in CP PvP. Combat has always been fast in CP because CP increases damage by more than it does defenses. CP PvP allows regen builds that don't drop a beat on spamming purge, which completely counters any kind of dot damage, while dots in no CP pvp where ridiculously hard for most classes to deal with and heal through with little counter.

At the same token, this scale back in dot dps has literally made some of the high end trial content impossible in PvE and not helped new players engage in content.

I still think they need to really look at the battle spirit system again, and do more with it to differentiate between cyrodiil, battlegrounds and PvE. They have plenty of opportunity like adding extra impen and lowering health regen, tweaking health pools higher etc for Cyrodiil that will help the content with lag and make it more accessible to people, without affecting battlegrounds (which tend to be a little better balanced imo).

Edit Note: Somehow I mentioned the wrong company because I was listening to a youtuber complain about the other company >_>

Well, my tankplar is able to hold her 🏠 in this patch.
