I would not be interested in a game with an increased pace, myself. In the MMOs I've played, I've really disliked playing alongside people who blast through missions at high speed. I prefer a slower pace for three reasons:
First, the scenery is part of the appeal of an MMO to me. In MMO player "personality" tests, I'm often characterized as, in part, an "explorer." The ambience, the setting, and the background graphics are all important parts of the experience for me. If I could literally stop to smell the roses, I would.
Second, I prefer a more cerebral gaming style. Problem-solving rather than "zerging." The best combats for me are puzzles in themselves, involving tactics - timing & terrain - and some amount of planning and preparation. In the particular case of TSW, one of the classic humans-vs-monsters myths is about brains overcoming brawn; the heroes facing down a terrible danger with cunning, courage, and guile. A normal man can't simply brawl with a werewolf or a Deep One.
Third, when I play an MMORPG, I like to roleplay and engage with my teammates. Every MMORPG I've ever played has been a poor single-player game, and also a poor multi-player combat game. I played "Fallout 3" and "Company of Heroes" to death, for instance, and I had fun with "Team Fortress", although it couldn't hold my attention. No MMORPG I've played has ever done what those games do, half as well as they do them.
So if I'm not enjoying cooperative PvE in large game spaces that are fun to explore, there's not much point in playing an MMO, for me. In my experience, a high tempo compromises both of those aspects of gameplay.
