Quick summary of the situation:The Sentinel pushed toplane with five people. And at minute 40 they approche the Tier2 Tower. Abandon was farming jungle, which means there are only four players ready to defend. At 40:08 the Tower dies and Ursa (OP) tried to fight in a losing position. Pudge and Puck try to help and all three end up dying without getting a returnkill.
This leads to the situation DEVILHAND is referring to: 40:25 Furion teleported to the other side of the map to push the botlane, leaving abandon and Puck (who just respawned) alone to defend the barracks.
(40:35 / Allied) Dragon.Spear: ok time to report this ppinkl
(40:44 / Allied) Dragon.Spear: for not defending
At 40:44 Ursa was dead for 55s and Pudge was dead for 32s.
And after Brown told him to use his Ultimate to slow them down, he used it.
(40:56 / Allied) sisiliano: use ulti at leat
Ok this is how I see it: He had to choose if he wanted to fight a bad position with three players against five with the two potential following outcomes:
- successfully defend the barracks, which is highly unlikely
- try to defend and fail and endup feeding three more kills, which gives the opponent team the chance of taking more barracks or even finishing the game, because his team would be always down on players
He decided not to take the risk and toke the loss of the barracks and used the time to push the botlane to the enemy highground.
Even if you disagree with his decision, I do not see any intention of ruining the game on purpose.
