TL;DR: Nnew accounts spawn less minions on wave 2 then lvl10+ish accounts.

I got to know this by creating a new account that I'm gonna be using to play with my little nephew. Made another one to confirm and had the same result. Here is a the vid showcase:

I think this should be moderated too. To have it either all accounts must be lvl10 or above or something like that maybe?

Wow, that's really weird. Lvl 10+ should be mentioned in the rules.

We didn't new about this problem before, I'll add that as a rule for the new patch but i can't moderate the old runs since we weren't aware of this issues. The new rules will include account past lvl10 and we need to see the account lvl before the game start on the video.

That's fine, no problem at all! If it wasn't because I made the new account we wouldn't have seen this! I'm still curious if lvl 10 will be enough. I'll level the account and get back to everyone!
