This question already has an answer here:
I've been on the constant road of learning new concepts in OOP, Software Design, Architecture, etc. But there are times when you are in a team where those concepts are foreign to them and they don't have the time or the same eagerness to learn as you.
The problem is if you design your code the "right" way, the people who code with 2kLOC classes won't understand it. Would you sacrifice good coding principles to support your team? What about a scenario where this will be a long term arrangement?
