I'm with MunkiLord above for the most part.
I don't keep many enhancements in my base beyond the ones I tend to use on everyone:Kismets, Steadfast, Glads, LotG, Numinas and Miracles for the most part. Tough to explain the 8 sets each of Crushing Impacts and Kin Combat but what can you do.
Inflation wise i believe we will get some. Already see Purps routinely at 30 mill in the weekend which makes me giggle cause why you silly people. Figure it will cap at 50 and that will be that. (Granted that wint be till summer of 2020 but still...)
As far as storing for a rainy day I wouldnt bother honestly. Lots of influence to be easily made playing the market, farming if that's your thing or simply getting out there and beating up Hellions. I hear they have deep pockets.
Happy hunting.
