The PVP skill advancement

I think about how to improve PVP, I have been playing MOBA, looking at Counter Strike, and other E sport. I think about the US Military, and listen to old story about how the WWI and how it had these Leaps in Technologic innovation. PVP combat moves should be leaping in the same type of manner speaking. Take Bloodbath, you do Damage and get health back. But what is its Innovation. Let me built context.

IRL we live in a a Technologic era But what I have learn is we never really enter this era, and we will never leave this era. People are always trying new idea, and see what the answer are given back. PVP should become the Combat shooting Ranger.

Now back to BloodBath, if we build upon and advance it; MOBA logic is to create Bloodbath 2.0 do we +,-,*, or /. a New mode where Players can create a unique PVP moves. Do you choose to Buff the Damage, Debuff the a stat, or Multiply the Health back, and divide the cool down (GDC or ability)
