After reading the posts in this thread, the only thing I can say is relax :)
It's just a game that we are all passionent about. As much as we may like to think Diablo is perfect or the best game ever, there is serious flaws in terms of what classes can do what at certain levels. Every class in the game has it's prime. For paladins thats level2. We all know paladins are OP, no matter what crazy build they try.
I realllly think my assassin build would work over a paladin, but I also wasn't thinking about block. Maybe my smite would of helped if I had a chance to attack people.
I have been inticed by this ironman for a long time, but you also have to think that after a few times and people get experienced with it, they will know what to build. You can't force people who play to win to be creative and try something new.
The leveling up HC characters could be cool though.
Although SC2 would be much better. Diablo2 glory days ended a long time ago.
