I'm not the most 
ted writer so i cant 
tee that this will be to good so 
give me a chance. So i have some problems with the new way that we ban, for one thing people who main champs like yasuo, blitzcrank , Teemo, etc never get a chance to play them not only this but people dodge draft pick matches so much its insane, and the wait times have skyrocketed. One of the worst things is when both teams ban the same champs and it feels like you wasted a ban.
What data are you basing your skyrocketing wait times claim off of? Overall for me personally games start faster, dodges seem to happen less often, and cancer like yasuo can be banned in masse until riot finally fixes them.
From meddlers most recent thoughts post:
Some more 10 ban data
We did a bit more analysis of the impact of 10 bans earlier this week. Particularly interesting there was the distribution of how many unique champs are banned per game, which ended up being a higher number than expected. Two key data points from that below, bear in mind that these are averages though and will vary based off your MMR and the server you play on:
Around 70% of games have 9 or 10 unique champions banned
Less than 1% of games have 5 or 6 unique champions banned
We'll keep monitoring how ban usage changes over time of course, so more info to follow again at some point. Overall we're still really happy with how the revised ban system in matchmade games has gone, particularly the amount its sped up getting into game (lets players spend a larger proportion of their time on the more fun bits).
So based on their actual data compared to your anecdotal experiences, pre-game times are actually somewhat lower now, and 'wasted' bans aren't as common as people might think. I believe in a previous thread a rioter (probably also meddler) mentioned it was only really yasuo who was facing significantly higher ban time compared to the old system, so they're looking at yasuo to maybe see if they can do anything about that.
