As someone who pumps points into Wits like there's no tomorrow (and there won't be, because I'll be first!), I find humans very useful. Also, their capes win out over any argument in my mind.
Someone who doesn't need to go first to make the build work (warrior, mage, ect...)? Well if you don't plan to pump wits thats wasted points better spend elswhere. High wits or no wits. You can't just go for middle ground.
It's worth pointing out that even if your high wits character doesn't need to buff everyone as their first turn, they can delay that turn and get back-to-back turns on their next turn, usually when the enemy is closer, or your allies have set them up for you. High wits will always be useful, because the person who goes first can control the battlefield.
Solo-wise, humans even have an advantage right from the start. If they pump their bonus points into Wits, they'll be able to go first in every even-level fight. Now, granted, they don't have the insane bonuses a rogue Elf would, but that's a different discussion on the current overpowered Elf racial ability and the double-dipping nature of backstabbing.
On another note, Lizard's fire breath has more uses than just (pitiful) damage. I use it to ignite surfaces, both for offensive and defensive purposes. The extra intelligence can be useful on a warrior, to allow them to equip the higher level mage armors if needed.
The Dwarf ability can be used to protect an ally and clear some debuffs, and their extra strength is actually useful on a mage, as it'll allow them to equip the higher-level armor that requires more than 10 strength to even out their armor/magic armor amounts (going all mage armor would be bad, because their regular armor would be low).
