Strictly curious: did Riot secretly vastly change how dodge penalties work?

About 3, maybe 4 days ago, I accidentally didn't lock in a ban. While I was pretty miffed at that, considering it was the client acting silly (I kept clicking it, wouldn't actually ban it, had champ selected), and okay, whatever. 5 minute dodge timer. Again, not happy because it wasn't my fault but stuff happens.

JUST NOW...no other dodges or anything prior to the aforementioned one...and it's a 30 minute timer? What the bloody heck? I have never seen such a ridiculously scaling dodge timer.

If there's something I'm missing, I'd love to know but at the very least, get rid of the ban dodge thing. It's stressful enough trying to alter things on the fly to fit the new situations that the new rune system has given us and when you add all the other standard things that make you adjust in pre-game lobby, having this annoyance does absolutely no good to anyone. You can specifically select to not ban a champion so what's the difference?
