I played KR longer than most of the free to play (f2p) games on mobile. This is the best Gatcha game ever due to the fact that you do not lose your characters through sacrificing like other gatcha rpg mobile games. Very friendly to people who are just f2p players as most of these kind of games are pay to win (p2w). What are your thoughts?

I am looking for games that are more f2p friendly. I only know one other than KR which is Clash Royale.
