Legacy Mode: The Who

I don't think it's a good idea to have two separate combat systems either. I think it's silly with the introduction of Momentum. However, I'm willing to admit perhaps there are some reasons people want Legacy. Perhaps it's better for PKing? I've never been big into combat at all, and even though I'm maxed, I only did it because I felt like I had to. Reality is I'm a skiller and a social player and started playing runescape only after googling "mmorpgs that don't require combat".
I only hope this won't fragment the game and make combat even MORE confusing for someone like me who already has trouble with it. I took the time to learn EOC, which was a pain in the bum, and now that I've learned it, I feel like I'm going to have to evaluate which combat system is more beneficial in which situation. It's just meh, and I'm really really not interested.
Truth be told, I probably won't be doing combat now anyway.
