Correctly designing a networked Skill System

Hello,

I am entering a stage in a project where i am redesigning the base class for the skill to be used within photon cloud, here is the setup:

-they are used by every Unit ( player or enemy)
-skills will be prefabs loaded in the Unit as a child.
-Inside the skill we have a pool of renderer for example 1 ExplosionParticle if the skill can be used every 30 sec
-I will use an RPC which check (if i own the object >ExecuteLogic) we execute the logic like this for exemple:

Code (CSharp):

1.  
2. //[will be RPC Later]
3. public override void UseAbility()
4.     {
5.         base.UseAbility ();
6.      
7.         if (ExecuteLogic)
8.         {
9.             UseEnergy();
10.             SetBuffStats();
11.             _target.transform.SendMessage ("ReceiveBuff",buffStructure,SendMessageOptions.DontRequireReceiver);
12.         }
13.  
14.         //Spawn the Renderer +sound  on target
15.  
16.     }

-Each Unit Have a SkillTargetSlot, which is the enemy we are attacking, its synchronised using OnSerialize
-When the skill is activated the renderer+sound are parented & enabled into the target, when skill is over Disabled and reparented into the SkillParent

Code (CSharp):

1.  
2. //Triggered by event after UseAbility RPC
3. public override void DespawnAbility ()
4.     {
5.         base.DespawnAbility ();
6.         //Disable Renderer
7.         //Disable Sound
8.  
9.         //Renderer.parent = this
10.         //Sound.parent = this
11.     }

Well now considering this setup, what would be the Best/Simpliest solution:
- if i Want the Unit to be able to Swap Skills ( destroy/ instantiate a new one), should i use photonNetwork.instanciate to be sure every unit equip the same skill ?
- is it possible to avoid to have a photonView on EachSkill if i reference the Unit PhotonView?

Code (CSharp):

1. _caster.UnitPhotonView.Rpc(..);

Any advice on some change? better solution?
