I have played ranked through 3 seasons now, I am growing increasingly frustrated with the current set up.
I just joined a match and called top, nothing against that. I was just letting the group know what role i wanted to play. I lock in a champion and player #5 comes back and says he didn't see my call and is going top, I told him i did call it but he said he was going to pick a top champion regardless.
Now, I have to decide on whether i want to lose MORE ELO, or not play LoL for the rest of the day. I only had time for another match and this 30 minute timer has basically stopped me playing for the rest of the day.
I have a suggestion for Riot;
Similar to Blizzard with its Looking for Group, you queue up for a ranked match but even before you go into the match. You have to pick your role so you are grouped with people that make a match up. No clashing, and it will actually encourage people to try roles that are in high demand. Support for instance.
Also, i much preferred the 5 minute wait after leaving a ranked queue to a 30minute. Sure less people leave but i would rather have to wait a few more minutes for another group rather than be stuck with the complete idiot who wants to be support Darius.
