Some issues with the Plants
First off I want to say I think PvZ Heroes is a great game and I am enjoying playing it a bunch. I think the innovation of having the units fight in specific lines, plus the height/water columns adding variation is great. I also may be one of the few people who actually really like the block and even instant block (sometimes) system. It helps with bad draws although rarely enough to make it unfair.
That being said I think there are some major balancing issues with the game that are hindering it's growth..
As it stands, the plants are woefully underpowered when compared to the zombies. Now I havent experienced everything there is to do in this game yet, but from what I can tell, the Zombies have a big advantage by going first AND last. Graveyard cards not showing how much they spent plus the ability to drop creatures as tricks/tricks that produce creatures mean what is supposed to be the plants advantage quickly disappears. And then there's The Chickening. This is a 4 mana (I'm a magic player so I'll use those terms) one sided board wipe. SO many of the plants have toughness 2 or less. It makes the Mushroom decks, the ramp decks (more on those later) and just about every other plant decks aside from the nuts completely unplayable and you can have 4 of them easily! The plants have nothing even close to this. The Chickening needs fixing. Make it 6 mana, make it only hit creatures on the ground - SOMETHING. The zombies already have a huge advantage they don't need the most efficient board wipe ever made in any card game (aside from toxic deluge?) Oh on top of that the zombies get that 1 mana +2 toughness thing? I know a bunch of green pea shooting guys who could really use that and a bunch of undead jerks who really dont need it at all.
More on the plants - ramp decks are not really an option because the zombies have way too many ways to deal 1 or 2 damage very early. In magic, I can choose to not block with my mana dork but here if I play a sunflower turn one, its probably gone on turn 2 either from damage, a zombie or some other effect.
I just think the plants overall need a slight boost. Maybe more synergy? There are 2 life gain plants but only 1 real payoff card, there's really only like 2 mushrooms that payoff other mushrooms, but the zombies are all synergy and its great.
Also I think the game would really benefit from a cheaper pack price or at least 2 more cards in a pack. I know the model is Hearthstone for the packs, but this game is not hearthstone. You need to attract people to this game and more sales, more free gems, cheaper packs and more cards is a good way to help that out. Let people get the best decks possible it creates the metagame that serious players like and rewards casual players with cooler cards more often. Oh and are there any plans to get this game on consoles or steam? I REALLY think it would be great, easier to stream too.
Maybe Im wrong on some of this but something to think about at least. Looking forward to the next big update. Keep up the good work everyone!
