The point of the damage cap?

If, if, if, if, if.

The fact is that a static 1m damage cap is a terrible idea.

Its perfectly fine if the game isn't broken, a terrible idea is making items that give you 80% boss dmg+nebulite. And what is worse is having these types of items available twice on one character. The gear in the game is broken not the dmg cap. Don't even reply to this I'm done if your too stupid to see how horrible the potential+nebulite system pineappleed over the game.
Also do you remember a time when 99,999 was the cap and yet the only people who bitched about a higher dmg cap where Ams because if they got that they could be somewhat? useful at bosses. Then the dmg cap got raissed to 199,999 and every1 bitched for the 1mil dmg cap because potential came.
