  * what is であろう adding here?

  * The writers has obviously already finished the game, looking for a second opinion if that makes the use of ば in ...作品のまとまりを踏まえれ **ば** feel a bit awkward. Compare to "作品のまとまりを踏まえるだからこそ英断と言わざるを得ないでしょう" for instance.




This であろう is adding the nuance of "presumably" or "seemingly" to 敢えて.
それらを掘り下げなかった is an objective fact, but this author is not sure whether that
was intentional or unintentional. In other words, he _thinks_ they
_intentionally_ avoided 掘り下げ, but he is not totally sure about that.

踏まえる is a transitive verb meaning "to take ～ into account/consideration".
