Hello, new to the game in the last few weeks.
Where it is true that you don't often want 4x or 6x of a card, sometimes you do. For example, I have a beastmaster build that definitely wants 6x Falcon and 6x Fox. The trouble is, Falcons come 2 to a core set and 1 to a spell tome. That means I need to buy 3-6 products just to build the book that I want.
I know Game of Thrones LCG recently started selling sets that were complementary to the starter box, such that a player who had the starter and one of these had a playset of everything. It would be great if Mage Wars did this. I don't mind buying 2 things to get a playset from any given expansion, but I don't really want to have to buy more of that. Being asked to buy 3 core set just to play a book I want to is a turn-off for me, and its a turn-off for others who don't want to pay CCG prices to play a LCG style game.
(In shops in the last week I've been teaching people how to play, and several were like, "Nah, that game costs too much." referring to the need to buy duplicates.)
Anyhow, I don't really care how the problem is solved (always sell full sets, always sell half sets, make an advanced core with a full playset, sell singles) but I do care that it is solved. Access to cards is a huge issue in determining whether people get into this game or not, and I'd like it to be easier to get people into it.
