A question for the BLU peeps

Popular idiom

You can't put a square peg in a round hole. Sorry.

I think you didn't even read the article you linked. Not only did you use the wrong idiom, but you are also entirely incorrect.

You can fit a square peg in a round hole, and a round peg in a square hole. The peg simply needs to be small enough. It will not fit perfectly though, leaving spots "free". That is why it is an idiom about society. People not suited to some sort of society due to cultural, ideological or religious reasons still can (and do) live in it, but they never really "fit in" properly.
The use of this idiom that you presented is a modern take from people that were simply ignorant of its true meaning and butchered it up.

In terms of Blue Mage however that does not apply, due to pretty much all people understanding that Blue Mage cannot be allowed in Duty Finder with the ridiculously overpowered skills. The difference in opinion is on whether they should be removed/balanced or left.

But that leaves the option of there being perfectly balanced builds with developers forcing them in the content that requires that balance. Think about it like a moldable clay peg in any hole. It'll just fit right in whichever it's pushed into.
