Rage Quits

Here are 2 games that I've played recently, where you can see 2 purposeful abandonments:

It's very often something like this: enemy team is trying to gank 1 hero with their entire team. Ganked player informs us about it, we get there ASAP with Town Portal Scrolls. Their gank ends up in killing 3 of them while losing noone in our team. Pudge says: "gg noob team" and leaves.

Or Enchantress AFK farming Hand of Midas in jungle, Spectre AFK farming Hand of Midas on lane. Meanwhile we are killing them constantly. Eventually Enchantress leaves saying: " Spectre noob carry no wards no supp ez game".

My question is: after 1 Rage Quit, even without any report, you are in low-priority? The system can differ RQ from DC?

Nope, the system can't make the difference. However, abandons in ranked games are punished more severely than abandons in normal games.

Also, no, you won't be in low priority after one abandon, there must be more of them, like 2-3 abandons a month or something.

It's 2 in fairly quick succession, and I think its 6 games of low prio...

The first time I got DCd and couldnt reconnect I had 3 games in low priority though o_o

Was that recently? Because they changed that.

No, not recently it was shortly after I started playing.
Never knew they changed that. I never abandon games on purpose.
