Dynamic Queue lacks sense of achievement
This is my main problem with Dynamic queue.
Your current rank or division as a solo player no more commands the respect it once did. Before it used to be "OMG YOU ARE PLAT! YOU MUST BE SOOOOOO GOOD", now it's "You are diamond. Meh. Probably got carried". It trivializes the effort and hard work solo players used to get into high elo. This is a direct insult to solo players.
Riot need to fix this. Too many MOBAs are coming out this year to be taking such a huge risk.
