We always see things from how they affect us and we need to remain open minded and aware of how it affects others as a whole.
The economy of Splinterlands is one of the reasons it is so successful. Whilst yes you will get people in bronze league get upset if they stick around like you said they could find that they can still earn and rank up.
I remember when they last changed the ranking system. I was battling in Diamond league and before they changed it I even managed to do some battling in champions league. I now battle mostly in gold since that update but I am actually making way more DEC per day now then back then.
New players need to stick it out and realise if Splinterlands needs to keep the economy stable so we can all play to earn for years to come . Who knows in six months it could be these same players that stick it out that are telling the players of the future this same message.

Anyways that’s just my opinion.
