They recently did some major overhauls to the default Control Control Recovery in terms of stacking repeated crown control ontop of each other. See here: https://ravendawn.online/en/home/view/update-204-notes.
Stacking Crowd Control Buff as a numerical value in a primary stat (While I like the idea), would be extremely hard to balance. Since Dexterity already works in this regard to the main idea, I suggest aiming at the design of dexterity instead of at wisdom. The other stat which will have synergy with Crowd Control Recovery, and Dexterity is Movement speed on foot. This stat exists in the game, however it is not part of the Primary Stat system or part of gear stats.
The major buff to crowd control was, however, only to Witchcraft Polymorph, Frog, Fear, which now silences. This ability is also very cancer in endgame content for Vampire Warlocks in Sovereign Crown.
My suggestion would be to look at Dexterity, which already serves these middle-ground scenerios. The addition of movement speed on foot or crowd control tenacity furthering the possibility for middle/ground/bruiser/more tenacious player development.
The problem of tenacity is also in the solution to tenacity, at the archetypes and give them all something similar to protection (which offers Crowd Control Recovery rate) as a 3 point passive ALSO WITH HAVING a cleanse, CC invulnerability of 8 seconds on unchained, maybe the best early-tier spells as well.
