It's about putting the advantage it offers into relation.
Except that you can build a character with 0 extra Wits.
If Wits is too strong, then what about Strength, Finesse and Intelligence which gets a lot more point allocation than Wits, Memory or Constitution because they are simply better?
Those 3 stats are actually forced on you or you can't even wear armor or weapon later on.
You can play the game without putting a single point into Wits.
The real reason Wit is so broken is because enemies squishies are broken. If you can gib the mages (and archer) before they get to act, the combat becomes wayyyyyyy easier because the Melee AI are still poor and that melee are only ridiculous if you go 2H build and abuse Teleport.
Like when we build characters, mages are the weakest because of how physical-magical armor work that only 1 mage is not sufficient so you have to trade the super easy physical damage for another mage if you want to go magical.
But enemy has like 2-3 mages in the team nearly every big fight with later some of them even throwing source spell around. With how majority of the CC in the game are magic-related, some random ambush without prepositioning abuse and low wit build will just result in a group CC to helpless deaths.
