i don't see your point. the puffer only has 1 more attack than the forest scorp upped and only 2 above the unupped. it costs 1 away from double the the scorps price.
Okay, so you believe it's logical for the Scorpion to cost less and therefore do less, but it's illogical for a Pufferfish to cost more and therefore do more than a Scorpion? I also noticed you left out the Pufferfish's increase in HP in comparison to the Scorpion completely, which is incomprehensible. Pufferfish is practically immune to CC, which Scorpion is not; it's a
perfect target for Adrenaline which Scorpion, despite it being capable of attacking four times with Adrenaline, is not; and Pufferfish cannot be stopped by nearly as many shields as Scorpion can. So if Scorpion had the same stats then I would be ecstatic, because Pufferfish's stats are just THAT ideal. To have it cost less or have better stats than this would just be absurd.
personally i'd rather it had lower health and lower cost to keep the balance than nothing at all. in fact the lower hp may be good as it induces poison when ingested. since it has 5 hp now it takes an upped oty with some kind of boost to eat it and get poisoned. so while the defence creature who is meant to protect sits calmly around doing nothing all the other creatures are being eaten. so lower the health and the cost and i'll be even happier. and you get to keep your balance. everyone wins (except the oty).
This is the first time I've ever heard someone complain that a creature not getting eaten would be a bad thing. Also, the Pufferfish would be poisoning your opponent this entire time, so it's by no means just sitting around and doing nothing. I stand by Zblader's explanation 100%.
