This may be a very weird viewpoint but how I see Splinterlands is like this:
Wild = Bot Format, take my cards and go get some [RoI]. I use XBot because Sylar is the guy who designed/runs XBot and he also protects Splinterlands from bot abuse.
Modern = too expensive for me to play at a high level, I just couldn't afford to get all those Rebellion Cards I needed.
Brawl = where I play my games against human opponents for [fun]
Tournaments = where I play against human opponents for [Frustration] lol jk
There are currently three modes of play where you can't bot... but having a format where you are essentially "Staking Assets" for RoI is not a bad idea imo... but that's just how I see things and of course everyone sees things differently.
However, one thing I see has been said time and again... "Observe what works well in other Web3 games and do that..."
I can't stress this enough - that's so important to do!!!!! We don't need to reinvent the wheel... just need to adapt the current wheels that work, refine and improve them and then BOOM!!!
