I agree whole heartedly about the fact of a flaw and playing it out, after all this is a Role Playing Game. But I stopped leaving it to chance about 3 campaigns ago when one of my players managed to have his way with probability right in front of me and get the following rolls: 13, 14, 16, 16, 18, 18. This was using the same method you are currently using. When I proceeded to ask the player to re-roll one of the eighteens, he threw a fit.
I let him play with it and all it caused was issues. First, this guy hit like a truck and took hits like one as well (18's into Str and Con as a fighter with his +2 racial into Str). Second, he was better than the rest of the party, one player had rolled no higher than a 15.
In the end I feel the point buy system is way more stable and gives the player more control while putting his limitations in his hands. Every swing, save, and skill is decided by chance in this game, why not let them control a bit more. It is also easier to DM with, easily gauging the strength of the party based on how many points you give them. I also think this answers the idea of a flaw because If a player wants (depending on how many points alloted) for every high stat they will have a low stat.
In conclusion, the guy on the forums was right, it's not particularly wise to play a dwarf sorcerer for mechanics sake, but it also isn't wise to charge into the lair of a black dragon, but I know I've done both so who really cares![]()
I would have a hissy fit if I rolled this well and the DM didn't allow it. Part of the fun of rolling is getting the chance to play a truly spectacular character. I have seen it happen once in awhile in the games I play.
We had a guy roll what was basically a 56 point buy character. He made an awesome paladin. The rest of us were not jealous or feeling like we were nothing but his sidekicks.
I didn't see it unbalancing the game play he didn't cake walk through everything and things were not harder for the rest of us. The funny thing in the end it was his character that died overwhelmed by vampires while the rest of us escaped.
