I've been dodging regularly to avoid terrible bullying enemy team comps, however never gotten blocked from the queue for longer than 6 minutes. The intervals between the dodges is more than 10 hours most of the time, yet I still lose 10 LP for each dodge. The support page mentions that (for 5v5 Solo/Duo Queue) for 1 single dodge you get a 6-minute penalty and lose 3 LP. However I only get the 6-minute penalty but lose 10 LP. This has happened 3 times already.
