So...

Wrecking crew was the most dull and easy thing my friend and I had ever played. Never felt interesting or threatening, wasn't just a cake walk but a dull cake walk. I was very disappointed.

Then we tried it with the new Heroic rules.

Wow! What a difference. Hard and fun, it was an amazing difference. It really pushed us and was a great experience.

Heroic is the redemption of Wrecking Crew! Give it a go, it's a real slugfest.

I love Wrecking Crew and have always thought they got a bad rap. Their decks are able to pull off some crazy combos but you need to see enough cards to make those combos actually happen. For that reason I feel like they have been an encounter I’ll only get out with 3 or 4 players. Solo or even 2 player they just dont flip over enough encounter cards. So heroic mode has definitely made smaller games viable with them. Hopefully they’ll start getting the love they deserve.

I think you're right that Wrecking Crew needed the expanded card draw of 3-4 players, as all the pieces to make it a great expansion were there. Two player it certainly wasn't fun. Until Heroic that is. It went from a D- to A+.

I’ve been meaning to try it on heroic, I definitely will now

Also try putting 1 threat per player on the main scheme each round or 2 per player if you are using BW+ (cards released in BW, or after) .
