The answer to your question is no. We played the game for about three weeks so I am have a little knowledge. So, here is why I say no.
An EQ character is about double as powerful as a DnD character. If you are wondering about the video game, the computer characters lvl is equal to half of EQ pnp character.
As for monsters, this is a much different situation. In our EQ game, I had to double the monster's CR. If the party was 3rd lvl, the monster CR should be 6. While at first I was concerned about hp differences (because EQ has about the same hp increments as DnD), the healers are so strong in healing magic that they kept up the hit points.
As for magic, EQ is much more combative in the spells like the computer game. This is actually kind of cool. A 1st level wizard can stand toe to toe with a warrior in terms of combat. This is a balance issue that I wish someone would fix in DnD. Also, casterr types all have buff spells that increase the stats of the characters. Apparently, EQ will have alot of temp. ability draining powers. The healers heal for a lot and the bards are just buffers with some healng, but bards can cast multiple spells at the same time.
That is all I can think of now. I kind of became frustrated with the DnD monster/EQ character incompatablity. We had fun though and powergaming casters at low level was nice for a change.
