2 bugs found pertaining to Warlord's Blood lust and disconnect during ranked champion select.
First bug: Warlord's Bloodlust attack speed doesn't work on Vayne. I held the show stats button down while auto attacking creeps, and my attack speed does not show going up nor down. No, it was not on cool down, it doesn't even show as a buff timer such as Grasp of the Undying, so I was unsure why it wasn't working.
Second bug: During a ranked game champion select notifications told me I disconnected from game, but everyone was still choosing champions. I was last pick and I couldn't pick my champion no matter how much I clicked. It doesn't make sense how everyone could still chat and choose champions and I couldn't do either.
