My guess would be something that is able to carry quite hard, meaning the player in question may probably be "Doing Fine" most games, getting kills et.c while the game is actually doing bad overall.
This has the effect that the player will feel like "Im awesome", but since he is still losing the fault must lie with his allies, as such he begins to road to "Flaming" his allies because they obviously aren't playing as good as him with the awesome CreepScore he has due to him only farming all game while his allies die fighting important battles over important objectives.
This whole effect becomes stronger if the hero in question is a common Tournament pick and as such is considered "Very Viable".
The player has seen the Champion being played well in Tournament Streams, and as such he knows its a good champ, if he doesn't win it's because of "Noob Allies".
As such, my guess would either be an AD carry, or a common Top pick.
Ashe, Ezreal, Graves perhaps even Corky.
