You ALWAYS level up his ult as leveling up will increase the damage dealt, which in turn will increase his sustain gained from it. The effectiveness his ult provides to keep him alive is a must albeit the minor increase in damage. The fact that the base cost doesn't change per level up makes it ever the reason to upgrade it. The higher increase in mana costs per second may seem a little heavy but you won't really notice its burdening effect on your mana pool until his ult has been activated for a good while, in which mana management will ocme heavily into play.
