In most cases thats ok because you can track it from the skill you got it from. What about when you get it from alchemy potions(Essense of Immovability)?
The main issue its not about if it got activated or if it's active, but while there's no active effect showing, you cant track whats the remaining time of it to adjust your gameplay.
Since the rest of the buffs you get from alchemy potions (e.g. magicka/stamina/health recovery) have an active effect showing why knockback/disable effect immunity, which is way more important at battlefield,doesnt have one? Am I missing something?
