Few bugs in champions.
1st. I'm not sure is it supposed to be like it is now, but E skill of Lux is now almost invisible. You can't see it coming and i can't see explosion area good.
2nd. When using trying to lasthit minion with Q of Nasus, and minion dies right before it, Q goes to cooldown. I think that is not supposed to go to cooldown, even when animation has already started.
3rd. Not sure about this anymore. but few days ago First skillshot of Xerath's ult was always hitting right to the Xeraths feet. Everytime when i tried to hit it, it just explosed to myself.
4th. This is not bug, so sorry but im still writing this to same text. Would it be hard to change teambuilders build mode so that you can find another premade players too. That could make gamefinding faster.
Sorry for bad english. I hope this will help you.
