Some people put the min/maxing meta over their freedom and fun. I've lost count of how many times I've read people complaining about "my static is making me change from X class to Y class, I don't like that class but I have to learn it and play".

Personally, I would never be ok with this type of decision, and I know a lot of people agree with me. That's just their way of playing, so taking the "best combination" as a norm is quite unreasonable.
