Wits isn't a shit stat. It's not something you're gonna focus on, but if you never invest in wits you're probably gonna be screwed whenever you face larger groups of enemies in tactician or later on in the game. Especially since enemies usually get great positioning, like an archer with high ground that can shoot ricochet into your tightly bunched group and break half your armor first turn. So humans might be at a tad of a disadvantage at level one, but by level 6 if your human rogue has different stats than your elven rogue then you obviously enjoy being hit by every single enemy out there before you even move. It's still possible to win the Early Access first chapter on classic mode like that, but I doubt it will be that way once the full release comes out.
Honestly by level 6 the racial bonuses to stats mean very little, and they will mean progressively less as you level. Even playing a dwarven mage with 2 points in strength you'll never use is no huge deal by then. It won't be balanced, it won't be optimal, but even in tactician it will still probably be viable (since in a game that isn't focused only on pvp, viable isn't the same thing as balanced, viable just means completing the game is possible with that race/class).
However I'm still never gonna play as a dwarven mage. If I play as a race I'm GONNA use that racial bonus cuz it pisses me the hell off to have a stat with points invested that I'm never gonna use. I'm no minmaxer, I'll play suboptimal classes just because they are more fun, but it's annoying as hell to have poorly invested stats. I think it offends my sense of neatness and organization. I'd rather the racial combat bonuses just didn't exist at all and Larian focused on balancing the racial skills.
In which case, yeah, getting a free AP on an elf is too good. Much better than encourage, even if encourage DOES scale to give 4 or even 5 attribute points by end game. Because by end game, you're gonna have a lot of points, so the extra 5 isn't going to make a huge difference. But you'll never get more than 4 ap, so an extra 25% will always be awesome.
Assuming they dont change the skills at release, i think you forgot how broken it is to start first as a party of 4 then run adrenaline + skin graft. Slap a double flesh sacrifice and may be glass cannons too. Lets make it even more broken with the 20+ ap combo that is time wrap. You can teleport up to 6 enemies across the map together then proceed to aoe them to oblivion.
Also that extra AP is a free sneak/buff or whatever, and 10% more damage.
Constitution isnt important right now because once your armor is off you get chain stunned by AI anyway.
