FPS takes skill, RPG takes nothing but being more powerful than the other guy and zero skill. When you win in RPG pvp you didn't win anything, your character won. that's lame. In FPS, when you win, YOU won, not your toon. I have always resented RPG combat but I understand it is a necessesary evil because of current bandwidth constraints. It comes down to your personal values...if you want your characters power to be more important than your own skills, then RPG combat is for you...if you are like me and you want your own skills to be more important than the power of your toon, then you will be like me and prefer FPS.
But the fact of the matter is both take time. In RPG it takes time to grind your characters level up. In an FPS it takes time to learn the physics and animations of the game well enough to line up your attacks accurately more frequently so you don't miss or get hit as often. Those people that are really good at FPS combat didn't get that good overnight. They practiced hard, I know because I lived it. I still play halflife 2 now. I lose quite bit but I don't mind losing when I know I lost because I had less skills than the other players and not solely because my toon was less powerful. My ideal game would have both skill and power. As you level your toon deals more damage and has more HP but twitch skills determine whether you hit or miss and not those random "to hit chances" that require no skill on the players part. That being said I don't want the RPG combat games to go away because I know that not everyone is as elite with theirs as I am. I realize not everybody has fast hands and eyes like me and they need something that's more their pace. But us RPG loving FPS lovers need some MMORPG love too. so I hope some QUALITY mmorp games that cater to our preferred method of combat come out in the near future.
