Hello. Long story short:

• Played with 4 other friends (EUW).
• Matched up against another 5-men team.
• Enemy team's players all have high ping (100+).
• They peek and easily get frags most of the time.
• We lost.

Normally, I expect people with high ping to have issue while playing, but they actually seemed to perform even better.

I know there's this topic regarding "peeking advatange" (I'm quite ignorant about it) but is it even possible to "abuse" it? I guess they queued by selecting another server.

TL;DR: 5v5 with enemy team with 100+ ping. Abusing peek advatange?
