Noob: guild, team, practically everything

Hi! I'm a new player coming from Gumballs.

So far the game has been fun with some serious bottleneck but that's OK for a casual level 45+ player.

I've tried to wrap my mind about a good combo team, but practically every suggested one required an SP that of course I can't have, or some SB but I can't find the skin sales. I supposed the page is with the market but not always on.

So, I've a bunch of characters: yan-bo, karrnulla, nolva, roger, ned... Should I just level them waiting for a skin, or is there a decent combo team that i can start using?

I could list them all if necessary, unless there is a way to link them.

Second point: I'm in an alliance, but the chat is dead sadly. Could you suggest me one that is friendly, casual, alive and possibly helpful? For me, the community aspect in a game is fundamental.

Thanks in advance!
