It's a very good suggestion. I'm trying PvP with unarmed char right now, I have to say it is a bit hard. There is a very little pros and a lot of cons.
Pros:
-You don't get the first shot, you don't have weapons
-You can easily knockback
-You're good against snipers, but you need to be in front of them
-When you're in front of someone you catch his attention, good point for your allies
-You don't need hard stuff to fight, you are the first on the battlefield and you loose an epsilon when you die
-If you have sneak, you are the cheapest and fastest scout able to fight
Cons:
-You need a lot of HPs, or a very good sneak
-Hard to level-up without playing experiences
-Hard to reach someone without sneak
-Armored and drugged soldier are hard to kill
-Good kicks or punchs needs 8-9AP with HtH Attacks
-You need patience
-YOU CAN'T RUN AND ATTACK
-Items like knuckles are useless, a strong punch with 6STR is better than Spiked Knuckles
-You are not very efficient in teambattle
-->The primary issue that must be fixed is attack & running.
--> Revorking some useless perks is a very good idea
-->Make melee weapon/knuckles usefull, if you are able to perform a Haymaker, why can't you with a knuckle ? It is possible to perform special punch with a weapon ?
I add idea about sneak and Hth
While sneaking ONLY, Silent Death should have a bonus crit(or more damage) for the first attack in the back
Avv, how can you loose a kick you master by dying ? This idea will ruin MORE unarmed than ever. Special attacks are not overpowered, I find them quite weak actually, 10AP for a piercing kick in the eyes with Bonus HtH attacks is hard...
