The thing that cooldowns prevent in other MMOs, mainly is an "arms race" in 1 v1 and to an extent x v x PvP. What do I mean?
Well for example take a sorcerer and nightblade. Nightblade has a gap closer, sorcerer has a gap opener. Both of these have no cooldown and a high magicka cost. So am I wrong in predicting that basically for the entire match it will be a endless game of cat and mouse, hopping to and away until both of these players get down to very low magicka levels so they can't perform it any more?
To an extent this is even true for CC. We know that breaking out from CC is a repeatable action with a high stamina cost- wouldn't this pretty much put the battle into terms of who runs out first? The victim with their stamina, or the CC'er with their magicka?
Basically, it becomes a battle of health/stamina/magicka pools...anybody have any input?
