I mean you know where I stand already :)
I played Splinterlands for years, stopped because it just felt like a grind with no upside. Took a 2 year break and came back and it was fun again because I was collecting new cards and playing with new abilities and such.
Then the last 2 seasons before Conclave Arcana... sucked. I just honestly stopped playing Modern games because what was the point? A Win ratio of like 30%? yeah that's not worth it. Could I play better and more strategically? sure. But when I have only level 1 and maybe a couple lvl 2 summoners and I go up against fully maxed out decks.. it's pointless.
So yes I think drastic changes should be made for AT LEAST the Modern format because if I was a brand new player who started last season.. I doubt I would stay around and keep playing because there would be no point.
