Yes, and if they go with their idea of tenacity stacking to 100, im proposing a way to better balance it.
Lets say each stack currently gives 10% bonus damage, now at 100 stacks thats 1000% bonus damage. Now just imaging a mage walking through everyone arcane explosioning, instantly killing everyone around him while he is also extreamly hard to kill due to so much hp.
Thats not balanced or fun. Instead make single target critical hits deal more damage, so it stops massive aoe, but it gives counterplay.
Now lets say a mage ice novas a group of players, then ice lances them. High crit chance from frost talents, shatter, exc. He can jow 1 pop almost anyone eith an ice lance crit, but this has counterplay. Freedom, dispels, exc drastically reduces his chance to crit because he loses the shatter bonus crit chance.
The idea is that people with 100 tenacity will still be hard to kill but they wont 1 shot you with no chance to survive and not have aoe spam going to evaporate an entire raid in 1-2 spell casts.
They could even make tenacity give a stacking damage buff whike they sre in combat but CCing the player will reduce the stacks. Being balanced in a way that if your team is focusing on CC they can keep the 100 tenacity player from getting to much bonus damage.
An example of this is for every 3 seconds the player isnt CCed while in combat with an enemy they get XĂ·2 bonus damage to all damage done for every 3 seconds they are CCed they lose XĂ·4 bonus damage.
So at 100 stacks, 3 seconds of not being CCed while fighting enemy players means you deal 50% more damagez at 6 seconds its 100% and so on, but there is counterplay in the fact that you can make them lose stacks if you CC them long enough.
The idea is to add some counterplay vs 100 stack tenacity players because if it goes in just how it worker at the end of wotlk, a 100 stack healer will be 1 shoting people with spells like holy nova. A druid with thorns is going to basically kill all melee without ever hitting them back.
Each stack of tenacity in wotlk gave 14% bonus damage done (or at least the last version of it i looked at) at 100 stacks thats 1400% bonus damage. Just think for a moment.
Rank 8 thorns does 73 damage when struck. (Domt remember if thats 100% accurate of the spell but this is an example) so 73X14 is 1022 damage. Basically meaning anyone buffed with thorns and has 100 tenacity stacks will kill most melee that are hitting them without even actually hitting them back. This isnt even with the player with tenacity attacking…
Thats why i want it a little more balanced IF they do chose the 100 tenacity direction.
