she's not under powered... what?
people must be playing her horribly horribly wrong if they think she's bad.
Sej can be powerful under the right circumstances. But overall, she's clearly underpowered. She's TERRIBLY weak early on to a ridiculous degree, she's massively item dependant, her kit has glaring, blatant flaws that limit her usefulness and, as has been pointed out COUNTLESS times, there are several other champs who do more or less the same things as her but are simply stronger in many ways.
I'm sick of this "if you think Sej is UP you must be just bad" garbage. I've crushed opponents as Sej. But that's not enough to delude me into overlooking her massive flaws. And Riot have deliberately ignored her practically ever since her release. And I'm sick of it.
