A small Karthus change idea
Right now his passive is with a fixed time of 7 seconds in all stages of the game. Why not make it like so that he remains until his mana is depleted like if he dies with say 70% for example he will remain untill it is depleted but all mana costs are doubled (otherwise he would be too strong). Imagine the typical scenario of Karthus teleporting in the baron pit to stop the enemies, very rarely he succeds in stoping the enemy due to the fact that he almost instantly dies and does not do much, and the enemy escapes before he can get them low enough with his q's (he can only q 2 times currently before being unable to cast ult). But if he has control of how long he can remain by managing his q's he can use his ult with his last 400 mana for level 3 ult (since the cost is doubled after death) he would do much more and would offer more flexibility as a champion. Thoughts?
