Yes.
There is no reason you can't partition your harvest: 50% into Pools, 50% into DEC for stuff...
Or, like I was telling AZ the other day - I don't have an efficiency issue with my Land... I have a Wallet issue!
Trying to keep moving forward with:
Modern Deck
CA Conflict Prep
Guild Stuff
Rental Cards
Land Prep
Kelan Gaines final purchases
Pickle Prep
It's a LOT and I don't produce anywhere NEAR $20/day from my Land... well... not yet anyway lol
For me - much like azircon, I harvest my plots... I take the DEC and power up another slot... or buy a card for a slot etc...
