It's only since recently that they started asking us players for an opinion. Apparently, it is impossible to apply true real-time RPG combat system in a game that has more than one character. When that is the case, the game resembles RTS or an action game. Because the characters gradually develop and advance through levels, you don't feel easy about losing them in a simple skirmish with a monster just because you didn't give out the order for them to move out of his way, and he squished them with his mallet. The ultimate goal of every developer is to create a hybrid game that will be compatible with all combat systems.
Lets wait and see.
For now, I am rooting for the BioWare guys and their Infinity engine. The RPG's you play in first person have a long way ahead, and yet to prove themselves and totally replace FPS games as we know them today. It alters the game from a CRPG to an action game which is good for all the FPS players. Pause, issue orders, unpause, all hell breaks loose, pause, realize you just made a critical error which could have been caught early had the game been turn-based. So which system is best for online games.
