Team has 12 deaths in <11 mins.

12 deaths for a team in 11 minutes isn't bad.

Honestly. That's 2-3 deaths per person in 11 minutes. I assume you guys have kills too?

This is the reason why lower elo sucks, people don't learn from there mistakes but they just repeat what they did wrong. Oh I died to a Lucian and Thresh lane and he has BF sword, let me go aggressive again on them again and lets see what happens

ive seen double that before so in the grand scheme of thing it isnt that bad if you are doing well in your lane then you maybe able to carry, unless you are a tank top then prolly gg.

Here is the breakdown from what i have seen:

If you are top and playing a hypercarry like Riven or Fiora then you can tp bot half the time and help them land kills.

If mid, you can roam bot lane to get them back on track if they are behind, if you are farming decently and doing at least moderately well in mid you can still kill their bot lane, mid lane champs are generally designed to be able to do so.

If jg, this is pretty self explanatory, you can help out struggling lanes or help get lanes that are doing well pushed even further ahead.

If adc, as long as you can get some decent farm, even if your supp is making mistakes you generally can capitalize on them. As long as your supp is the only one dieing you are fine for the most part.

Supp, if you can prevent your adc from making dump choices and keep them alive then your adc should be able to farm up enough to make an impact on the game which leaves you the chance to help support people struggling.

The key to all of these factors though is that it depends entirely on how well YOU are playing. If you are doing poorly yourself there is no room to complain, if you know you could do better there is no room to complain. Also, some games you just cant win and you have to accept that. i dont know anyone with a 100% WR.

I've beaten that score by myself before.
