I play mostly 2 out of the 8 factions, and atm I am hesitant to spend any money on packs because of how many different factions it includes, which I barely use at all. I think it would be nice to be able to cross out a couple of factions from the purchase, so I don't need to get so many runes which I don't want. Especially when paying with cash. Protectorate/Wrath would be ok I suppose
Also, you could check PoxBox if you want to exchange the runes you aren't able to trade with people. It's pretty cool nowadays.
Hopefully the expansions will give more faction focused options. I can definitely sympathize with not wanting to pull from such a large pool when you only use 1 or 2 factions.
