This is due to everyone moving at the same speed right now, mostly.
Look up how fights looked in LiF, everyone were pretty much running at the same speed. If someone didn't want to fight they'd a vast majority of the time get away. Only way to deal with that would be using the few methods of chasing people down, a shout that made people fall over if they ran away from you(bleh), mounts, group formation speed boosts and ranged weapons.
Speed is relative, we right now have no difference in player speeds at all, when we do then sure, you'll be able to be a faster than the average character. But what happens when you run into someone who is just as fast as you? You'll end up with the same situation we have now.
If you boost character speeds by 100% of now, it doesn't matter. Since everyone will be moving at that speed so it doesn't really solve the "issue".
The only thing higher movement speeds will achieve is as as Teknique mentioned OOT, that running into a static group of people and then running out will be a much shorter affair. But, if the opponent is moving or able to move due to spacing towards your group, then more movement speed is irrelevant. Its still a relative speed and you are all moving at the same pace.
If you are thinking im against different races having different stats, then you are reading text that isn't there. Im talking about current issues, due to current state of characters.
that sounds stupid. like some god damn swords and sandals combat. i just scream really loud and you fall over.
