That last comment was really more in reference to the guy I used to play with. I haven't talked with you enough to get a fair picture of your playstyle, so I'm not at this point going to pretend that I can accurately guess the reasoning behind your decisions. Just saying that this guy I used to play with, that was exactly how he played- coming up with the numbers first and only later trying to wrap a character around them.
I'd still like to point out the point buy system and the fact that it's more fair- running the two sets of ability scores that have been generated so far, we have one character who's abilities total 19 points, and one who's abilities total 36 points. It's a pretty massive power discrepancy, and situations like that are why most groups I know have gone to point buy.

Most GMs I have run across require a lot more than that kind of tactic, they generally try to push their players more and make people think outside the box while also having the core bases covered. That is why I am giving us basic caster support and a meat shield with either class I picked as we lacked both.
Same for me, and I think that's part of the reason I like wizards more- usually, if our party just got into a routine for "do stuff this way, you win again", our DM would come up with ways that forced us to do something differently. Spam haste for most fights? He'd find some way to make that stop being optimal. It's no fun if it's just routine.
