I like the new system more, in implementation. Potency wise it needs a lot of buffs to justify how unforgiving and frustrating it is. I'd also say give each card part of it's old function back (besides spire, make that give something else and balance can give DH) in addition to the effects we have now. That way it wouldn't be just damage cards, you could play it like the old days to some extent. But they won't ever revert to the old system IMO. Too much of a balance nightmare.
