Suggestion for karthus's ult
Reduce damage to 250/350/450
can be charged up to 10 seconds. Minimum of 2 seconds for 50% damage maximum of 10 seconds for 150% damage if charged for 5 seconds or more slows targets for 30%-99% if used while passive is active, activating the ability will automatically charge it to 4 seconds and will not apply slow
I realize this might be a tad overly powerful, but he cant fully charge it without giving the enemy a small window to recall, and considering how strong mobile midlaners are right now, i want to see an imobile mage to get some love. The numbers would have to be adjusted, but i want to see him be able to charge his ultimate for more damage.
