EDITED: Original thread was about strength giving HP. I've expanded it to include my thoughts on other stats.
I honestly don't understand what the purpose of being a plate class is any more; They're nerfing plate (and mail) armor in WoD, and HP has been largely similar for a long time. Hell, locks and druids with heart of the wild have more health than tanks!
I feel like something has to be done to return us to the RPG equilibrium of 'warrior has most health'; I don't much care for reasons of balance, but if you wish to nitpick we could bring up the fact warrior has little to nothing in ways of direct healing and yet has to constantly stand near things that really want to kill it.
So my proposal is simple: what if strength gave half the hp value of stamina?
(Original thread ends here)
With that I also had a few thoughts on how WoW went about handling it's stats from vanilla to WoD. I do like the removal of hit and expertise as they were largely little but taxing those who can't get it (which, with wow's way about content, is nobody). However, I really think they should review some of the stats and make things a little simpler.
Currently we have one base stat for each class (str, agi or int), a bunch of spec-only useful stats (spirit, bonus armor). Then we have versatility, haste, crit, mastery, multistrike. And then we have stamina, which just comes free with higher item level.
My opinion: Ratings should just go, with a lot of their benefits rolled into original stats. Gear will have a combination of said stats.
Rough sketch of how the new 'simplified' stats will work:
Strength will increase melee damage, health, melee/ranged critical strike damage and armor.
Agility will increase melee damage, ranged damage, melee / ranged crit strike chance.
Intellect will increase spell damage, spell crit chance and reduce resource cost of abilities by a tiny amount.
Spirit will increase healing, increase resource regeneration, reduce cooldown on abilities and increase chance of procs (including trinkets / weapons) by a tiny amount.
I feel like haste is responsible for a lot of classes feeling 'slow' - they're designed to NEED haste, so why not just stop dancing around the bush and remove it / tune specs dependant on it accordingly?
Mastery... Once again, there's no reason it has to be a stat. Why not just make it a small passive bonus that serves as a tuning knob when something needs adjustment?
Multistrike is basically the same as crit. I've no idea why it's needed.
Those are my thoughts on stats in WoW. What'd you guys think? Will simplicity feel better or are you in favour of 12 more ratings added for your min-maxing pleasure?
