The new queue feels bad
The new queue in my opinion has not been very good. It added length to queue times, where I use to only have to wait a minute max I can now wait up to 3-4 minutes and I am only at gold elo. I am sure it is much much worse at higher elos. This problem is made worse by the next problem: people dodge way more then they use to because of people showing their intent. When someone dodges it throws you back into a multi-minute wait again. On top of that it is very common to see 2-3 dodges before you actually complete a queue. Meaning their has been times where I have waited 10+ plus minutes just to start playing.
It also seems like games are way more lopsided now that people only play 2 roles. Although this just might be the balance currently.
Dynamic queue also hasn't really seemed to solve much for people getting their roles either. I main mid and whatever I put as my secondary I almost always get. I actually get my main role less now then I use to with the old system. People who put support or fill also get screwed and almost always get support. So from my perspective a ton of time was adding to the queues only for me to get the role I want less of the time. In my opinion dynamic queue as is has been a huge failure and has not delivered on anything it promised and made me wait longer to give me a worse experience. To top it off team builder was removed and so now we have no way to practice specific champions, instead we just have to pray that the queue gods will grant us our role and that someone won't dodge. I am sorry but I expected something substantially better then this product that was forced on us.
