Rock Garden, Ick Swamp, and Grimm's Grotto

Rock Garden and Ick Swamp
I think these two levels should be reclassified as "normal" difficulty. They've always been the easiest of the hard difficulty dungeons, and I really don't think they merit the classification anymore. The only thing that makes these levels remotely difficult is that they have a tendency to block you off with nasty status effect plants and their bosses have high resists. However, the actual strength of those bosses is fairly suspect. Finding Binlor to use stone heart in either case is a huge advantage, and anyone smart enough to bring a really big sword will be in for a cake-walk.
The Rock Garden in particular now allows you to accrue many spoons, which individually are quite weak but can add up to 10 or 15 base attack. Basically unless you get unlucky with plant placement it's a simple and straightforward level, and I'd go so far as to say it's easier than Double-Doom. Sure, if you get the Bandit or the Gorgon double-doom is going to be straightforward, but get Frank or Bleaty and you're in for the fight of your life.
Grimm's Grotto
On the other end of the spectrum, I think it's time to promote Grimm's Grotto to hard difficulty. It's always been the most difficulty "normal" scenario by a significant margin, and I've long found it ironic that it's significantly more difficult than Rock Garden. This level has super-charged monsters and bosses, and the boss is also random so you have no way of prepping the right tools to take him down. Sure, you might get lucky and get Medusa, but you could just as easily pull Bleaty.
