I hate the large maps. I just want to play the smaller ones, because most of the large maps just suck. And why do people with full gear (bought with crystals ofc) get matched with new players who don't even have materials to forge one piece? Real balance right there. Pay or lose.

well generally speaking the matching system is rather good currently, it does try and match you with players around your level. sometimes they are lower than and sometimes they are higher. the reason for this is there isnt a huge amount of player's currently playing the game at one time on average so instead of having you wait for 15mins for a game with peep's who are all at your level it tries and matches you with ones who, for example are either 4 levels higher or lower (just a guess =P )

also they may add it in later for people to choose what maps ect they want to play but currently if they did that then it would take even longer to find game's as players would be split up in to many different queues.

so i'm guessing until the game becomes alot more popular and their is a constant high of player's available and looking for the game we are going to have to endure =P...and trust me when you get higher it get's worse haha due to the fact that there are less high level players than low...currently im level 13 and keep getting put in games with level 18's

Hmm.

One suggestion be made, instead of choosing a map. You could choose what kind of game mode you want(?).

This way or another, some maps won't be played much (or even at all), and that's not good. That's how developers explain the reason.
