Well, Light Armor Optimization is IMHO the most powerful approved LEW feat that I've seen, and a must have for any light armor wearer, so I can understand that. My dervish is planning on taking the feat soon. I think at Level 5, which is the first free feat she has.
Medium Armor Optimization gives back some movement, which is nice, and makes medium armor interesting. I was just wondering if someone had an idea for a heavy armor optimization feat. To balance it with Light Armor, you'd either need to give max dex back, or just give a flat ac bonus. To balance it with Medium, you'd need something like reduced movement penalties or something.
Just curious. Not sure how it would be done or if someone had it out there already.
