Uh, Remake still works, even though someone died.

I've never had a problem remaking after first blood.

I think the vote already called so it ok to die when the vote already out there; I think.

It only applies under specific criteria.

Will edit post when I find them.

UPDATED: If any player is dc’d or flagged afk for at least 90 seconds at the three minute mark, a /remake is available UPDATED: A first blood against a player’s team before they leave/dc prevents a remake vote

They changed the idea after they realized enemy teams would level 1 dive the team with 4 players just to get first blood and cancel the remake option.

they changed it

First blood only cancels if they AFK happens after it. If someone is DCed from the start of the game, and then first blood occurs, remake will still go through
