Re: Bought Toxic Brainz from Gnome Guy and I don't have it!
Unless you get extremely lucky, you're unlikely to get more than one or two legendary stickers before you have all of the other characters. For a point of reference, I've just finished getting the legendaries after having spent just over 31M coins. I got lucky and got one or two of those stickers from the community chests.
I strongly encourage you to try multiplayer more as time goes by. In turf takeover, it doesn't matter if you suck. You earn 1K coins per minute in the game. So if you play a game that goes all the way, even if you don't kill a single thing, you'll earn 20-25K. A half a year ago, I hated playing multiplayer for the same reason as you. But as long as I keep playing the game I keep improving, and now I'm often near the top of the leaderboards. If you like playing sunflower or scientist, try establishing a safe place somewhat near the action and just support your team. You can still end up on the podium as heal master. Playing against humans sharpens your skills, but it takes patience.
I find in this game that the more I stretch my comfort zone and try new things, the more fun I end up having.
