i dont think nocturn ulti can be considered healthy anymore with the state of damage creep
in season 3-5 i never really had an issue with it... it starting getting annoying in 6-7 and now its just absurd
the burst damage he can do plus the over 2 second fear and the spellshield means u really have no way of trading him after his ulti
i feel is instead of losing all vision.. u lose all vision NOT seen from champions
so all vision from wars and minions goes dark... but u can still see your allies and thier little bubble of vision, i do get that the cooldown is long... but when its up. its pretty much a free kill.
last game i even knew which ally he was going toward.. i was running toward them.. but i stil had no idea wtf was going on in that fight.
i feel i should be allowed to see at least the circle around my 4 allied champs.. if nothing else
