They need to alter the rate at which F2P can accrue cards, or this is gonna flop. but they claim they're looking into that. Right now, you can get a pack per HUNDRED wins, which is only 5 cards. So basically, buck fifty, or 40 hours. sounds legit. Needs to be like a pack an hour if you're winning if you want people to actually play it f2P (which you need to keep the community alive, and those players will supplement with real packs if they're playing).
gameplaywise, lack of instants makes some things really bullshit. I get why they don't have them, but the legendaries are literally pay to win in some situations. I don't care how good you are or how well your deck is made, the ability to bring out one of the broken legendaries and immediately stealth it, leaves you unable to deal with it with most decks. I had an opponent at like 6 hp, basically 1-2 turns out depending on what I drew, while I had like 19 life, and had that big of a swing in a single turn EVEN THOUGH I had removal waiting in my hand for him to drop bombs. Assassinate, Backstab, and Betrayal in hand, like the best removal in the game, even if I'd had something like a fan of knives it wouldn't have saved me. To me, that's a sign that, yeah, legendaries are fun to have be op, when you can counter them. But there's LITERALLY nothing I could do. Super fucking annoying.
