So, we've played all 3 and are in the middle of Mummy's Mask as a 6 player extravaganza each time. Some thoughts:
Right now, I'm bored with PACG. The card mechanics for the most part are static and stale. Triggered is cool, except now everyone except the Ectomancer or someone who has a built in evade simply just doesn't scout because, at least that I can remember, there aren't many beneficial (if any) Triggered Triggers. Combat is king. Smash big numbers and don't bring anything else to your deck. Why isn't there Combat Ranged X / Combat Melee X*2? Birds should be far easier to kill with a bow than a blade. Second to damage, Damage is queen. Fail a barrier, combat, shake the wrong lizard's hand and you're discarding / recharging some armor from your hand.
Secondly, spells. Undead Gremlin (made up example) has Combat 14 / Divine 8. Even if I have D10+2 for divine, I'm going to load my deck with Holy Light to roll 2D12+D10+2 because those numbers are more likely to hit 14 than my D10+2 to hit 8. If something is suspectible to magic, maybe have Combat 14 / Spell 10 and have your spells be for a Spell check. That's not the most elegant fix but I just know that for the most part, I've never done the (or) for a monster fight. It's always fire the most dice I have at the Combat check because that's the best odds. The only time I might consider the (or) is if I get caught without an attack spell in my hand.
The above has led to everyone at our table basically having the same decks just with different named cards for the most part. Flip a card with the mentality of making sure you can tank some damage, do the card and repeat.
With that said: Curses are nifty. We need more effects like that. That force you out of the normal do a roll, tank the damage, hunt and move on. Maybe instead of damage, creatures start shuffling other creatures into locations? Or Ogre Name #3 hits you, take 0 damage but place this card next to your character. Your hand size is -2 until healed. Maybe a barrier that if you fail, forces you to explore random locations?
Side note: Armies. Good pumpkins. Please save "ARMY" traits for bosses or at least giant cards meant to scare the life out of you. In Wrath, we were facing Armies what seemed like every 4th card we flipped and it was just unfun. Especially with the numbers they require.
