Riot Please: LeBlanc
How do we go about a mixture between new LeBlanc and old LeBlanc?
Why not simply decrease the time for sigil to activate based on current AP? This way you get the best of both worlds as far as you were asking, time to kill, while still scaling into the game without being unnecessarily painful for LeBlanc or their opponent.
That would work far better than this stuff, lol.
