Fun game my friends and I play some weekends. Would recommend playing in unranked/qm after the first round.
Drink once if:
Very good pregame if you and your friends play video games together. Anyone else have any?
Are you trying to kill people? 
One/death sure… but, uh… # drinks per death seems… deadly.
You obviously do not play front line heroes!
I routinely have 3-5 deaths (or more >.<) in QM when playing tanks or bruisers, especially when you get the “no healer” matches. My last game of the night was the classic QM “no tank, no healer, GOGOGOGO!” It was on Braxis, with us: Imperius, Artanis (I had a rough night in HotS, so this was me playing something I like to unwind a bit), Raynor, Kel’thu-FREAKIN’-zad, and Falstad against Leoric, TLV, Nazeebo, Malthael, and Zul’jin. We had a fairly epic team fight over nothing (QM, so … yeah), where I tanked them like a boss, died (our Imperius was chasing various Vikings around somewhere else on the map), but traded 3 of them for me, so it was clearly a “My life for Aiur!” moment. I think I ended up with 4 deaths total, and that was just one match.
My liver is clearly not cut out for this game.
Take a shot everytime someone writes insults in chat.
I can’t believe you didn’t think of this one, it’s the only rule you need.
Sounds fun.
New rules: take a drink everytime you hear certain quotes
“MY HUSBAND IS DEAD”
Or maybe everytime an allied hero talks to you.
Alarak: Ive known much better healers
drink when someone leaves the game for at least a min?
Can always take a drink each time you’re paired with a Varian in QM, and you have no tank but the enemy does, so he goes twin blades. Drink every time he dies 
Poor Murky mains
And The Lost Vikings.
No, I think Shadowmere is trying to do a sincere PSA to stop those people who might go on losing streaks. Follow his rules, if you do poorly in one game you’ve most likely passed out, so no losing streaks. 
You would die from overdrinking.
Play Aba and not get out of hall of storms 
at least you will survive one or 2 games
