Is there a particular reason she's not in this patch? yet everything else besides the skins (which I honestly could care less about) is being released as the exact same damn time when they've all been worked on for pretty much the same amount of time. That being roughly ya know, three weeks

Can we actually download the patch yet? I'm pretty sure they just put her on the champion roster as locked content till she can be bought.

Furthermore, if the patch is today, she should be out within the week.

oh i know she'll be out this week, i just find it kinda underhanded that everyone gets to have fun with the reworks while the people who've been waiting for lissandra have to sit in the corner and qq over it lol.
As for the patch the notes are on the launcher but not in effect yet and probably wont be till tonight.

I do not see the big deal since riot even explicitly said they were slowing down champion creation to 3-4 weeks per champion.

Because that's what they do with all new champions.

They havent released a champ with the patch for a long time, how long does it take people to actually catch wind of this?

She'll probably come out Thursday or Friday like they always do.
