Yeah soz mate, that entire thread is technical feedback on the new ladder/league software, I was very much speaking from how I was building the system to function for the future. I didn't realize people dont know that i'm not a CSGO admin and I hadn't consulted with any CSGO admins when I posted that message. The finals format is decided/posted before the start of the season and this system wasn't built until now, future seasons will now take advantage of it.
But I definitely assumed wrong in that post and I can understand why you feel misled. That said, my message pretty clearly said it was from a "technical standpoint" and that you should check with the CSGO admins.
Anyway, sorry about that and good luck in the finals.
