I like playing without procs, I am more than happy to keep playing without them. However it does make build diversity very boring(obviously) and I would much prefer the rules be extended to conditional stat sets. Briarheart, burning spellweave and clever as a few examples.
Saying that I don't think proc users need their own campaign especially if that might mean all conditional stat sets go with them and the only way to have a more interesting build is to play with proc users(I don't mean to make proc user sound like a dirty word lol).
My suggestion is simple. Can we do what many people have suggested we do through out the proc meta and simply balance them. Scale proc damage down to that of an equivalent skill and then let it scale exactly the same. With your damage. Let them crit, make them useful for pve content and make malacath an option instead of BIS.
I don't think cyrodill in its current state justifies any more campaigns and I genuinely like the option of all the sets. Even if I hate free damage and free healing sets. I would rather play against people using proc sets than having loads of different versions of PvP.
These are just my thoughts, feel free to add yours below:
