I still wish pvp and pve balancing would be seperated, because I do see the need to rework in pvp sometimes, but not in the same way in pve.
I stopped renewing my builds, and almost stopped playing because the work on a build was wrecked regularly, and keeping up took too much time instead of enjoying playing with the builds.
I realize that this may not be what you're looking for, but the answer to your question imo is... are your friends still here?
I know for me, I would move on to new single player games frequently but what makes mmos different is that your friends are here, and the model of an mmo IS to shake up the meta, regularly, to give you a reason to keep playing, re-grinding content, and trying other things (classes, play styles, etc.).
There is a tough line the devs have to walk to keep things fresh while not frustrating players so much that they leave. I'm not sure ZOS has been on the right side of that line, lately, but to be fair I don't think it is easy.
But if this were a single player game, if combat/playstyle/etc was significantly changed to no longer be the game I enjoyed... I would move on to the next thing. So to me the incentive is friends / the community.
If that's not an incentive for you, then it is much simpler... is there anything else in the game you enjoy doing? If not... there isn't one.
Happened to my NB in 2016. Happened to my Sorc in 2018. Happened to my Sorc again in U34, and then my longest running main since the game came out, my main since 2014, my Templar, in U35.
Worst part. Templar won't be fixed. Even if they buff the class or give it some other kit with skill utility changes, the likelihood of ZoS reverting Jabs to its old animation is close to non-existent. They can nerf a class into obscurity, make sets that were good bad, they can make a playstyle not good for a while, and it will eventually bounce back. Always does. But changing the animation on a skill can make or break a class. And unfortunately, the new Jabs animation is bad and won't ever not be bad.
The animation is an improvement. It better fits the timing of the skill and is easier to see when stacked in a group. Sure it looked awkward for a bit but after killing a few world bosses you get used to it and hardly notice it at all. Templars could use a bit of help but a change in animation isn't that help.
The animation is not an improvement. I'm a professional animator, and can tell you that it ignores the principles of animation. It looks awkward because it's not animated correctly, and you can get used to bad animation, but that doesn't change the fact that it is bad animation. The original animation was done well, too, so it's just a terrible change.
Yes, the timing of the skill, as in its cast time in ESO terms, is fine. Its timing in animation terms is terrible. They could fix the animation with, LITERALLY, less than 2 hours of work by a single animator on staff. It's not a difficult fix, I could fix it in 30 minutes if I was given the tools and the files used by ZoS for animation in ESO. The issue lies with timing, and if it was timed properly, it would actually look fine. I don't like that they reuse that vampire spear motif, but if the animation was good, I'd be able to overlook it. But the animation isn't good.
The new animation is much easier to see when stacked as a group. That alone makes it superior to the old animation. The old animation wouldn't fit the change to the skill firing so if timing is your issue the old animation would be much much worse.
