When did you play conquest ? In Core set for netrunner..... most android netrunner economies looked similar as well regardless of faction ... you played all the economy cards available because you just needed too. In similar fashion, there just aren't that many economic options for the cards yet. The only econ engine you list that has been around since core is Opus, and the only other one that is still seeing play is Desperado + Datasucker. None of those other economic engines existed until at least the second cycle. Warhammer hasn't got it's first big box yet. Think of the first big box netrunner cards... Dirty Laundry, Professional Contacts, Daily Casts... Same Old Thing(ok corp not so great but yeah, these are all huge cards and 3 of them are still staples, pro co just won nats...)
Corp side I played Beanstalks for the longest time out of faction just because I had too..
I'm not even sure what economies your talking about in warhammer, since most of the economic supports aren't played and the economic battle really takes place in the command struggle, which is a pretty interesting dynamic and one of my favorite parts of the game. If your argument is that every faction lives and dies by the command struggle, I see your point, I'm not sure how to win on certain planet flops(where you can't win in 3-4 planets) without participating in the command struggle game. So yes everyone has to play cheap units and participate or get crushed, people still manage to win regionals with big Chaos units somehow though.
Warhammer needs a bit more to hook people into it I agree, it doesn't have that really cool asymmetric netrunner feel, it doesn't have as strong of a theme/thematic hook except for people already into warhammer 40k(I'm personally not, this is my first experience with 40k) but it's still actually a pretty decent game and the mechanics are fairly solid. There is a LOT of places to mess up in this game, and skill really does show through imo. (Although I still think Netrunner is extremely skill intensive, I am going to refrain from getting in the argument of which one is better fpr testing skill I think its silly. I think good players consistently win in both games and that is enough for me)
I play / have played upwards of 12+? ccg/tcg/lcg, and I don't know of a single one where a really really bad draw won't screw you. In Netrunner there is really bad agenda flood(remember they printed jackson howard at some point ... don't count out conquest cards of that nature in the future to deal with being command screwed early)... in Magic you got mana flood/screw(its really hard to win when you play 4 spells and they play 14), and then in Conquest you can not draw any units(happened to @Ossa once). Some games are worse about it then others, but I haven't found Conquest to be particularly bad. As the power level of non-signature cards increases over time, I feel like the impact of the 1 of signatures that I find to be a little bit too powerful lessens. I really wish we could free deck build but oh well.
Conquest isn't in my top 2 games I play even, but I thought I'd give it some love in this thread cause everyone is so down on it :D. Everyone go play Aunshi, Eldar, Coteaz, or Zarathur, ( I find all of these to be interesting). I've heard good things about the new eldar mobile guy. If you want to win a regional Kith is a good choice :D.
