Please Don't Try to 1v5 in ARAM

A good majority of the ARAM games I won (and lost) are because someone was trying to 1v4/ 1v5 the enemy when their team isn't around. This gives the enemy an easy 5 or more kill advantage and 1 player who can't contribute anything. I just had a Fizz who kept diving 1v5 and then blaming our team when we can't 4v5 after he dies soloing. I politely ask him to 'stay with the team plz' and all this does is make him flame more for the rest of the game and keeps diving 1v5. if it wasn't for this Fizz we had a pretty good team.

Please don't ruin ARAM by trying to solo 1v5, unless you're a fed Yi. This also applies to Summoner's Rift, but I feel it's easier for 1 player to get fed enough to 1v5 in SR than in HA
