Solo Que

Why we do not return to the old system of solo que, that is Heler Caster and Mele, and much more balanced, many situations arise where in 70% of cases there are war pala or war dk, where the heler especially if he is a priest is impossible win, I believe that in only that there must be this difference, hindsight it is a normal 3v3, where the shovel and dk warirors are advantaged and priests and low geaar in general are clearly disadvantaged

War/DK teams are winnable even if you are a priest but heavily rely on your team mates to peel for you and to not make a single mistake. One mistake would cost you the game. And pray for some RNG dmg to kill someone quickly. However, as we know, its soloQ and most people make a lot of mistakes.

The problem with the old system I remember that some setups are dominating such as "Hunter/aff lock/heal"

Still, the work around this system to not be abused or completely unfair is to create some kind of a way to make it for certain setups to less likely to occur multiple times in a row. I presented my suggestion here : http://forum.warmane.com/showthread.php?t=433993

Basically create an internal avoid system so that when 3 players paired up in the same team 3 times in a row, they will be put on an internal avoid for a duration of time. Meaning that they will not play with each other for that period. This means :
1- They wont have the same "OP" or "Weak" setup they had more often
2- People cannot abuse the MMR system to queue up together every time (because people have been doing that and it is like 3 premade guys with discord vs 3- completely random people with no way to communicate.)
4- It will break the cycle of "2400 MMR people vs 1400 MMR people) since they will have to be paired with lower MMR guys if no similar mmr found duo to the internal avoid.

Yeah, this might lead to a longer queue, but I think if balance was found, more people will be queuing. It might even become more challenging to play solo queue.
