That's a real stretch there. Why do you keep wanting to make this game more like an action game? There are already other games out there like this. Recently I decided to give Devilian a try and it seems to be more like what you are looking for in a game. It's basically an ARPG(Diablo 3, Path of Exile) mixed with an MMORPG. It plays like an ARPG, but is in a persistent world like an MMORPG. It's actually pretty fun so far.
