I suggest that the characters be allowed to start with a flavor feat at level one, which would be limited to a handful of choices, and maybe get a chance to pick another one at level six. That's all. The list to choose from wouldn't include things like ability increases or gwm or alert.
I second this, I specifically remember in the old D&D games such as Neverwinter Nights starting you with a free feat, hell even old Icewind Dale, not to mention you would be able to get things like snake blood. The game looks like it's missing a ton of feats and aren't many for spellcasters. For example subvocal casting, allowing you to cast spells while silenced or deafened. There was also blind fighting, that's self explanatory and I'm pretty sure I could list more if I went digging.
