P2P does take more skill then F2P, you have to actually learn how to use hotkeys to get yourself through p2p. Also the tanking is far more of a challenge then f2p tanking, you have to shark,brew,pneck then restore afterwards to get your mage/range lvl back up. Plus its way harder to drag, the freezes are 15 seconds & don't get me started on d scim specs cause you really need to know how to tank for like 5 seconds with no pray up lol.
F2P on the other hand, is quite simple. All you need to do is stick with the group & shoot your arrows & go in for scims when told to. It takes less skill because your callers are pretty much telling you when to switch prayers and when to go in for scims and when to pull out with range. Also when tanking all you need to do is spam click pizza's, thats not hard at all & you can do better in the war if you have 20-25 def gear.
