I'm calling crap that players with more skill points would be OP. I've played with moded characters at my bud's place and, despite having all skills unlocked, I wasn't "one-man-armying" my way through enemies. Sure I felt powerful, but shouldn't you feel powerful at the lvl cap? I know I certainly don't in the regular game when I can get killed in seconds by some pack of bandits with crap weapons, while I'm kited out in all legendarys.
But why are they so concerned with players being OP? I've been completely unable to fight bosses without resorting to bug exploitation and glitches. For example: The Badassasaurus fight in the Torque DLC was completely unwinable, even with a full party. The only way we beat him was by throwing Deliverance (http://borderlands.wikia.com/wiki/Deliverance) under the door over and over until we won. And we're all level 50.
And I know that you can disable his attacks by blowing up barrels on his body, but we couldn't get close. As soon as we exposed any part of our pathetically weak and squishy LVL 50 bodies we got hit with homing missiles and died.
We had to completely give up on the Pete the Invincible fight because we couldn't find any way to glitch him out. Also when he hit us with his AOE Acid Attack and we had to get under the water pipes to wash it off, swarms of lvl 66 spider ants would come out of the pipes and kill us anyway.
And yes I know you're supposed to swap between the two pipes, but trying to think about that sort of thing is a bit hard when you're covered in acid and a guy is chasing you with flamethrowers. It probably would have been winnable if turning on the pipes didn't cause a bunch of Mobs to spawn and try to kill you and you alone before fighting each other.
