I don't think they should turn off the rewards - they just need to implement the staking requirements or link them to Splinterlands.

What I mean by that is I don't want to have to choose between staking on Splinterlands or Soulkeep...

I have a good chunk of staked SPS and I don't want to have to then start staking more SPS on a different game.

I agree though - staking requirements should be a thing and it could be tiered:

League 1 = 1X Staking Req (SR)
League 2 = 2X SR
League 3 = 3X SR

Etc, etc, etc
