Who cares if anyone is "power-playing"? Plus usually those power items are hard to reach, either worn by powerful characters (you need to be strong enough to kill them or have good enough sneak skill to steal them) or hidden within dangerous dungeons. Who'd waste all his money on potions and such so you can get inside a dangerous dungeon to steel a strong item? Again, who cares if someone does? As long as I'm fine with my playstyle - and why shouldn't I be? unless the game has elements that makes it less enjoyable - well, there's not problem at all. If anyone loves power playing, as long as he's okay with it it's fine I guess. Not that I care about this anyway.
Don't care. If I don't like the level limit, I'll just CS or console-command around it. :shrug:
This. Seriously, why bother with this when half the players can work around it if there's a problem?
