So i have played over 100 demigod matches when the game came out. I've learned the ropes and was pretty good but i took a break from the game while they fixed all the issues. I come back and now they have stat tracking the bad thing is it doesn't have any of my previous games listed so it looks like ive only played like 5 games. So now im trying to join some pick up games and I get kicked because they think im new. And now again I am tempted to quit this game because even though i want to play i cannot get into a game. sucks.
Ye just wait it out, or join noob games.
But to be honest, you sould join noob games anyway. If you only played 100 games you still count as a noob. Just play some and you will feel it. IF you join a mid or high kill game, you will get stomped so hard, you wont to it again 
There is a reason why ppl dont want 100games or 150games ppl on their team. 99% of them just suck hard ( compared to the rest of their team). So dont take it personal, this game just needs a lot of training to be competitiv on higher skill lvls.
