I agree with the original poster. If you want to see a truly innovative system, look at
Planetside. They use "cerification points" , and different things cost different amount of cert. points. For example, a level 10 Character might have around 15 cert. points. Sniper Equipment is 4, Flying Scout vehicle is 3, Heavy Weapon is 4, Heavy Armor is 4, Cloaking Gear is 2, Trike is 1, Light tank is 2, etc.....
So as you level up you can "cert" in more things. Obviously you cant use everything at once but as you level up, you get more options.
It is a great system and Webzen should take a really close look at it.
Note - There are some contradictions going on with webzen and the "class" system. I have seen where they say there will be 3 classes (short range, medium range, and long range) but then they also say you can mix and match gear. This begs the question -- WHY even have the three classes if you can mix and match gear anyway?
