Survival PvP Ideas

I now play MM and BM and am pretty successfull in those specs but I miss Survival for PvP so I was thinking black arrow should be changed for 100% uptime and should also heal you for a percentage of its damage done to add some survivability to the survival spec. Also the counterattack talent should be removed and replaced with a Camouflage buffing talent that makes it full stealth like a rogue or druid. I feel like those two ideas would really help Survival become fun again in PvP. What do you guys think? Suggest your own ideas also ^_^
Explosive Shot: Now deals 1xx% weapon damage as fire damage + 2 charges of RAP.

Black Arrow: Focus cost reduced to 20 and damage increased 10%. When dispelled, heals the Hunter for 5% health per remaining tick.

Counterattack: Baseline ability. You have a 25% chance after receiving a melee critical strike to lash out at your target dealing 200% weapon damage and rooting them for 5 seconds. 20 second CD.

Lock n Load: No longer affects Arcane Shot. 30 sec ICD when proccing from traps (due to new Explosive damage.)

TNT: Black Arrow chance to proc increased to 20%. Activates a 9 second ICD on Lock n Loads triggered by Black Arrow and activates the trap ICD.

Mirrored Blades removed. New talent "W/e you want to call it." : During Deterrance, the Hunter is still able to shoot but cannot generate focus.
