DnD4 - Quick and dirty class-less solution

The DnD-classes are made to fit different roles within a combat. As such they do a good job. However, some genres don't lend themselves to hard and fast classes.

Here comes my humble suggestion on how to make DnD a bit less classy. The following factors are decided by class

• Hit Points and Healing surges
  
• Armor and Weapon profficiencies
• Bonus to defence
• Trained skills
• Class Features
• Powers and Utilities

I don't have suggestions to all of these, but I'll give you the ones I have

Hit Points
Hit Points = 2 x CON-Score. This seems about right for most classes. The Fighter, for instance, has hit points 15+CON. 15 also seems about right for a fighter to have as CON, so the hitpoints would be about 2xCON anyway.

Hit Points / Level
Most classes has 5 HP/ Level. The more fightery classes has 6/ Level, but to make things easy, go with 5

Healing Surges/ Day
6 + 2 x CON-modifier. Quickly eyeballing it from the other classes and following the same reasoning as for Hit Points.

Defences
It seems all the classes has +2 in defences to divide as they want

Class Features and Profficiencies
Don't know about these for the moment

Powers
I don't know how well this one works, and this is also the hardest one to balance. All characters have 2 at-will, 1 encounter and 1 daily power. These can be picked from any class. To put it another way around: Build a list of powers where you gather all the powers sorted according to level and "type" (at-will, encounter, daily or utility). The players can then choose from this list and don't have to care about classes at all.

Skills
This is a tough one as well. It seems most classes has 4-5 trained skills. Maybe you can start with 5 skills, or trade one skill for having more profficiencies.

That's my suggestions so far. I'll gladly accept feedback on this.
