Warrior, Rogue and Sorcerer. You could choose if you wanted to play as melee, range or casting character. But I always thought that Warrior was somewhat underwhelming even though he was my favourite character. He could (and still can) just hack and slash and cast low level spells.
The Belzebub mod addressed that by adding four new skills to every character and even added three new classes (of this Necromander is still unplayable) with their own skills. But one remains the same - everyone can cast spells as the Sorcerer.
It's rather dissapointing to see so few differences between them. And when you select Barbarian, Assassin or Necromancer, you even get the same models as before. I always felt a little cheated by it. I alway felt that the new classes are a bit alien and don't really belong to the game.
So what do I propose? Merge them. Let the player choose which path he wants to go. You don't need Barbarian to use axes more efficiently. Warrior is already strong melee character, so why won't you give him an ability that allows him to use two-handed weapons more skillfully?
Three classes are enough, it just needs variety. Something like skill tree that was introduced in Diablo 2. You could choose which skills you want to use and what skills you want to ignore. There could be skill tree that is more Warrior-like and skill tree that is more Barbarian-like. The same could be said for Rogue and Sorcerer. They just could have the abilities of the Assassin and the Necromancer. But it would be optional. But only the Sorcerer could use spells like Fireball or Chain Lightning.
Of course, that would change the core mechanics of the game. Spell books would not be relevant anymore, only to the Sorcerer. Does that mean that they would need to be removed? Absolutely no. They just could have different purpose. There could be some common curses that could be learned by all characters and some books could give you one talent point for example. So they could still be used by all characters.
Regarding scrolls, I think they could be removed, apart from Town Portal scroll and Identify scroll, and maybe few others (e.g. Ressurect).
To sum it up, I would like too see old classes improved rather then adding the new ones. To give them their own abilities, differentiate them and make them more replayable, so the spellbook could be removed and replaced with the skill sheet (see the pics).

What do you think about it? Is it too bold? Do you think it's interesting or do you like the current system more? I'd like to hear (read) your opinions. Thanks for you attention.
