Trying to play something new

The only game I know how to survive as a F2P is fire emblem heroes (looj at my username!) and today I decided to play another thing and now I'm lost.
My friends said that this game is full of whales and weird metas and if try to be F2P I'll rage-quit in few weeks.
I'm scared! What to do?
Strategies? Decks?
Or I'm just doomed by whales?
Tnx for your help!
