Yeah... if you have the EOS lying around under a mattress you may as well stake it anyway... you would need to in the same way that you need SP and rc to access the STEEM chain in a meaningful way.

The pop-ups from Scatter can be whitelisted for the application... which I should do... but it also done on a per-computer and per-node basis... which is a pain in the arse, as it also is per-transaction type! So, many things to whitelist...

Steem-monsters handles the chain transactions much better. Only at the start of the match (with the loading bar disguising it...) and the in the marketplace (or levelling cards). Apart from that, they don't need to keep making transactions on a fast basis (as far as I understand it!). That little lag when you combine a monster card... that is the lag that you get when you do stuff in EOS Knights... it's not much, but enough to get annoying after a while!
