Nah. I disagree. But then, you knew I would. Again, giving EVERYONE a free feat makes Variant Human not special, and it opens up for more imbalance issues.
Honestly, you must be the most imbalanced DM I've ever spoken with, rules imbalanced, that is. Do you just make up whatever you want when you play and ignore the rules a lot? I'm just curious. Not being mean here. I've just never met someone who said they were a long-standing DM who totally blasts the rules like you do.
As for the OP, I do use feats regularly. I wish more were available. I miss some of my favorites. Ability increases are boring to me. I do them when there is no feat I like for a character. So, Lae'zel usually gets a straight Ability increase because it works better for her, but other characters I go straight for the feats.
