Sion bug in nexus siege
Bug with sion in nexus siege:
What: On the attacking side, sion can get 100 crystals before the crystals start generating passively.
How: As sion, just die before crystals generate. I have only tested it with getting executed by towers, but I think it should work with player assisted suicide.
The effects: Sion is slightly less crap. Seeing as being a deployables bodyguard is the one thing he can do well early, it lets him match the power of other champs. I believe it also starts him regenerating crystals sooner than everyone, so there's that too.
