Yea, I have alot to thank Min/Maxers for. They helped me better understand exactly what I dont want 5e to evolve into. Im very thankful to them for that.
Edit (Just clarifying The above. It sounds a bit nasty and I dont mean it to be) : I was once putting together a SwordMage for an upcoming change of DM's (which never happened...sigh). I was curious as o "what was best". So I visited a CharOp Board. I read through the pages, drilled down on the feats, read which synergies to take and why, what my stats had to be ... and stopped.
I realized what I was doing. This is what contributed to my cancelling my Wow account. The obsession with the hyper-optomized character over just play whatever the hell you enjoy. This is D&D...its enjoyable because of taking on a personna, and I wasnt doing that...I was taking someone else'. I had forgotten what was important, put someone elses character on a piece of paper. There was no "Me" in it, no real character. Sure, it was mechanically effective, but it was soulless.
The funny thing was, I had to go to the CharOp boards to figure this out for myself, and so yes, the experience sorta helped me "hit rock bottom" so I could reflect and turn it around.
The really did help me understand exactly why I want 5e design to be mechanic light/fluff heavy, because thats the sort of game I enjoy. Ive grown out of hyper-configurable character mechanics, Im just over them.
So yea, I am thankful to the CharOp boards.
By the same token virtually every person on the CharOp boards would be happier if the power curve went from sky blue (great) to blue (good, and potentially great in many circumstances) with a small spattering of purple/sky blue (niche, great in only a few circumstances).
The black and red powers are things that no one really likes.
And if WotC listens to CharOp then they'd end up with a hell of a lot less balance issues that result in truly terrible choices.
