Sorry about that. I assumed you were pissed you couldnt get sej working based on your comments. Play how you like of course!
Not to offend, but you do always seem very focused on trying to "break the meta". Combine that with your "Shit is not fun" comment on Sej, and I figured I'd try giving you some advice. Your personality seems to be an anti-meta one, nothing wrong with that, I was in a GuildWars 1 guild for 3 years where every member's mission was to create janky-ass builds that didn't conform to the meta. Thing is, after being in that setting for 3 years, I've determined that the majority of jank is simply unfunto me. Of course when something works it's freaking hilarious and awesome.
Currently I just stick to the meta in all games I play now and simply try to outplay my opponents instead. But yea, continue experimenting if it's what you prefer.

Kass is banned cause he's still OP as fk. His changes made him super anti-mage and he's damn near uncatchable with the lower cooldown on riftwalks. He's probably more OP than before. AD can counter him harder but basically no AP mid can touch him.
