What about a way to way to do VATS in melee and Overload causing you some damage, but has a higher crit. chance?
And maybe Melee taking up less AP.
E.g. Running towards an enemy, you can overload their arm (Crit. skill) and stop them from firing. Then their leg and stop them from running.
I haven't used much melee, I am really sorry if these suggestions are stupid.
Also, with the 50% chance to not hit when 1hex away, what about if:
5 hexes away - 15% chance for them to miss.
4 Hexes - 30%
3 Hexes - 45%
2 Hexes- 60%
1 Hex - 75%
After all, the only people who could really risk it that close would be bursters, and if they're gonna miss they might want to run away. Cripple the leg, and you have a severe battle going on.
Just a suggestion, I'm not very good with melee so if stupid, sorry.
EDIT: I didn't want to spam a new topic with so many melee suggestions going on, and as it's related to overload and a lot of your ideas would work extremely well anyway, I thought to place here. Just delete it if it's placed wrong.
