New Battleground is 100% NOT New Player Friendly
I started playing last January. I just got my first 6 star last week. I do not expect to rank high at all or win even half of the matches, but there definitely exists a middle ground between that and getting thrown match after match against people with a full roster of max leveled 6 stars (so that there's really no difference wether I ban their 3 "Best" champions or not) that on top of that have increased Hp, Attack and Safeguard.
Either the matchmaking system needs to be reviewed so that it factors in Prestige/Total Base Hero Rating for the first couple of matches and as you climb through ranks it starts only factoring ranking.
Or the entire system needs to be reworked. I like the whole "Draft" idea a lot but it completely loses it's purpose if people can just fully deck with 6 star champions. So maybe make it so that you can allocate a certain amount of Champions per star rank (ie. five 6 stars, ten 5 stars, fifteen 4 stars, etc. etc.)
