I’m not sure if they need a nerf or not, but if something was done to either, I’d rather have it be done to both. Probably along the lines of the suggested short cooldown (3 secs max, maybe with the decreasing CD by 0.1 secs per spell level), but with other spells still available (the idea is that players should have to worry about what is at the arrival point and deal with it rather than rushing through the whole level without fighting a single mob).
