While i love most of this patch and specifically the glacial presence buff, there has been one issue I need to mention regarding magicka characters stun situations.
we are now down to 1 somewhat reliable non-class stun in the form of flame clench which very limiting for builds, down from 2 with vampire drain unfortunately the knockback is not always desirable. While I recognise that vampire drain was quite a cancer on the PvP community, we didn't have many options left to use for stunning. Shock clench was the best stun that Magden and Magcro had for a considerable amount of time and that was removed some time ago. All I ask is that we see changes to class stuns to make them more reliable for offensive play, as right now Arctic Blast and Bone Totem are defence-based AoE stuns that aren't very effective in a lot of scenarios, as Arctic Blast has a short duration and a small radius, and bone totem is a static ground AoE, meaning people can run out of it within the 2 seconds it takes to fear someone. Either class stuns should be changed so that they can be used more effectively in more scenarios like with the Arctic Blast 4.0 idea (which might require more time than you have at the moment), or we should see the return of a stun like shock clench on a magicka ability that doesn't require us to make significant changes to our build, that reliably stuns a single target. No cast time or delay for example.
potential targets for new stuns:
Frost Clench and Shock Clench, if you add a stun to Frost and Shock Clench, I'd suggest adding a unique secondary effect them, along with changing Flame Clench. Shock Clench already has an AoE effect so that that could stay. This change would ensure that all destruction staff users will have an adequate single target stun to use regardless of the state of their class-specific stun.
Inevitable Detonation (perhaps change name and functionality).
I understand that this might just be the first week and that you might have plans already to solve this issue, but in case you aren't aware, this post might help you.
