There's a lot of balancing to be done on the transition from DD to RR. Charms is one, stack up on vitality charms and you can have over 3000 hps on your character. My 39 hero has like 30 constitution because there's always stamina potions. Points are best spent on agility and strength. (agility until your chance to hit and dodge is maxed or high enough) The item randomizer needs a big looking into as well. Upgrade your silver armor into something inferior? How about your Dragon Breastplate, I got an "upgrade" to a white texted piece with ZERO stats, just 190 armor was all I got, luckily we all have to use the save/load trick to get anything decent in the first place. That shouldn't even be possible!

Frost is lame. It's like a pause button that effects only the monsters. Polymorph is lame too, it's like playing a developer mode game and using your own "hack" spell to race through mobs to test quests and what not. Hopefully RR will be rendered with more challenge in mind. I love to let the boss monsters go full strength at me, toe to toe. That's what a hero is about imo, taking it like a man.

I know how hard balancing is, I've played Everquest for over 3 years and yet they still balance things with their patches, often adding content to break things all over again. It's neverending. It's a quest of keeping it fun while making it challenging. Some people want it more fun, some want the challenge, you're never going to please everyone. Trying to please everyone will only end up with a broken game.
