I am just getting back into this game and realize I can't buy single packs from older sets. Why? Right now there's only Core Set, Extended Set, and this new set. Why no others? Are they bunched in with Core Set and Extended Set?
Yes. Core is all packs from poxnora release set to grimlic's descened. Extended from the one after grimlic's descend to the previous expansion.
This. And for me, this is not right, we need to ahve more packs/boxes, with 6 or 7 expnasions per box, or at least, choose the faction we want the runes, now, it's just hard to get the ruens you want/need by buying packs.
I kinda like it as it is in respect to faction unspecific . It helps building up a pool of runes in other factions which makes it way easier to try out builds outside your main faction.
