Eh, I was a min/maxer, and several others in the Legion on Liberty also seemed to be like that. But everyone was welcoming of new players, concept builds, etc... I'd say that the "elitist" style of min-maxers was greatly in the minority. CoH seemed like the game where, if your build showed that you were a noob, you'd get advice for how to improve the build, rather than a derogatory comment and then a kick from the team.
I tend to agree. I played exclusively on Virtue, I ran into a number of people who were
huge min-maxers, could do some really interesting stuff with their builds and had some epic toons for sure, but I don't recall ever being on a team where I was chastised for not having the right build, the right powers, the right enhancements etc. I had a couple of toons that I adored that I put a LOT of time into building, but even then I wasn't necessarily hard core min\maxing, I was mostly just chasing a couple of key stats, like my AR blaster having just insane damage. Most of my builds were made around concept, character or even just me saying "damn you know I never did try that powerset and it looks fun, what kind of character would use Stone armor?"
Even still, most people never seemed to care, even the ones who were really into their builds. I also found most people didn't even bother me about my build, even when I played characters that were a little gimped because I was still learning their powers or what ever. I think the vast majority of "advice" I got was when I asked for it, and then I'd get a ton of very helpful advice, and a few debates over the true utility of certain powers, but yeah. I was never harassed, never made to feel like I wasn't doing it right because I didn't min-max or what ever. I know some people like that were out there, but I think they were a small minority.
I do remember one time I was kicked off a team in a really weird manner by a crazy over the top guy, but that had nothing to do with min-maxing and apparently something to do with his odd little SG, but that is another story.
