Basically vk won the decider map breeze but used a glitched cypher cam in 6 rounds during defense(they only won 3 out of those 6 rounds). Ultimately riot gave ascend the win with a ruling that they deserve 6 rounds because of the glitch and 1 round for economic impact those 6 rounds would have caused. After the Brazilian region just out-cried their support against the ruling, they agreed for a re-match but with a 7-0 round advantage to ascend. They(VK) played really well and ultimately lost only 10-12 despite the 0-7 disadvantage.
The brazillian logic behind the 1st ruling(handing 7 rounds) was that the referee should have stopped the match in between and/or other teams(dapr from SEN) have used the same cam(which is false, with no evidence) and /or the glitch is not listed to be banned. Unfortunately the whole region is wrong since the ruling said that you can't put a cypher cam at places where it can't be seen and destroyed but shows you the enemy position, which the glitched cam shows. Also there have been two instances previously ( with vodafone giants and x10) using the same cam and teams using it had to forfeit the map later.
TLDR; riot should have just ff the map and gave the victory to ascend instead of changing the ruling two times. They didn't need to give round by round analysis in the 1st ruling. Also they didn't need to bend the rules to give a different ruling 2nd time and replay the match with ascend having an advantage. It should be similar to previous rulings for same incidents instead of it being changed for just this tournament.
