Re: Why should I play HERO?
The guidelines for creating new base classes were called Bard, Cleric, Druid, Fighter, Paladin, Ranger, Sorceror, and Wizard. Remember 3.0 and 3.5 were based on the, exceedingly faulty, 10 levels of Class Y is equal to 10 levels of Class X is equal to 5 levels each of classes Y and X. Of course their design team failed miserably at this, but it was a guideline. Usually I based new classes on the Rogue as I felt it was the best balanced 20 level class in the game.
The same applies for PrC's, of course the balance issues became even more disparate between the PrC's depending on requirements and the designers. I'm not calling these good guidelines, but they were there. WotC was fairly close lipped about their design guidelines, because they hadn't released those as open content. But I know plenty of experienced D&D players that have had no problems making their own classes, PrC's, and spells.
It is not as easy as HERO(part of the reason I made the switch), but it's not as hopeless as being painted in here either.
