Why did you have to disable Gangplank?
I'm as big a lore nerd as it gets, and I love it when lore affects gameplay.
But I don't like it when lore only LIMITS my gameplay. Its funny as a joke notification, but not if it's real. What about all the people who want to play Gangplank? He's a new champion with new mechanics; he's got a pretty high pick rate at the moment.
I hope you don't do something like this again in the future, and I hope this only persists for a day. (And seriously, why not capitalize on spooky gangplank?)
And honestly, who thinks he's ACTUALLY dead?
Fantasy setting. Explosion with some obvious survivors (like the ones trying to get on TF's and Graves' raft) No body produced. Bad ass main character.
There are plenty of champions who 'don't exist' with the lore in the state that it's in, and there are plenty of champions who are literally just dead.
