Be fair Riot. Give Lissandra the same mana regen you gave all casters.
Taken from the patch notes:
The following mages / tank supports are being changed to have 6 base mana regeneration (mp5) and +0.8 mana regeneration (mp5) growth stat: Ahri, Alistar, Anivia, Annie, Azir, Blitzcrank, Braum, Cassiopeia, Diana, Elise, Fiddlesticks, Fizz, Galio, Gragas, Heimerdinger, Jayce, Karma, Karthus, Kassadin, Kayle, LeBlanc, Leona, Lulu, Lux, Malzahar, Morgana, Nidalee, Orianna, Ryze, Swain, Syndra, Taric, Thresh, Twisted Fate, Veigar, Vel'koz, Viktor, Xerath, Ziggs, Zilean, Zyra
Lissandra still has 5.67 (+0.4) instead of 6 +0.8.
Why is Lissandra being penalized for her passive? Why doesn't Lee get reduced attackspeed because of his passive? Or Rengar reduced Flash range? (Note: These two above sentences are a joke. Showing how hilarious excluding Lissandra from the mage buff is)
Riot, why do you hate Lissandra?
can literally cast spells with 0 mana every 18 seconds. meaning that she will still have an ace in the hole for when you need it. so her mana regen may lower to compensate for free spells.
