Is it ok to afk when...
You support is feeding and mid is feeding. I honestly doont think its fair to ask me to go through potentially an hour of torture for people that dont "care" about winning.

Its never ok to go afk! 
No.
If they are intentionally feeding, just report them afterwards. No point in sinking down to their level (yes, you are at fault if you afk, and you're punishing the people ally and enemy alike for going afk). If they are feeding because they suck and/or having a bad game, then finish the game to the best of your ability without having an aneurysm.
I hear ya on that....ugh trolls.
When you're that good you shouldn't even worry about feeders.

Short of a real life emergency, the answer is always no.
