Lissandra's Mana Regen
I'm sure you've guys already tried something like this, but just curious if Riot has done a passive where she gains ~20-~40 mana regen per 5 each time an enemy is CC'd for 3 seconds, can stack as many times as possible. This will give her a late game 240 if she lands full team W and ult someone and Q a few people. Coupled with 100% base mana regen from items like athene's or morello's, it's about 480 just off of one basic combo, but only over 6 or so seconds. Thoughts?
