Remakes should be at 2 minutes, not 3
ESPECIALLY if the AFK is the Jungler. Not being able to have a leash (or set up your camps for Ivern and Shaco) is really hard to get ahead, or even contest with. You already are 1-2 levels under the opposing Jungler too. Same issue with solo lanes. You are already behind 1-3 waves too. Ant that is seriously disadvantageous when the opposing laner is level 2 or 3 and you are still level 1. Not to mention if they somehow got the wave to freeze on their end or the lane.
The early game is arguably the most important part of the game. So being behind because of an AFK who decided to reconnect at 2 minutes 59 seconds, is at the very least gong to be a very difficult game to win.
