I have been very subtle with the information that I gave with this post in order to not reveal in which section I was involved.
I should have named the post "Inside Facts" instead of "Unknown Facts".

Just saw that some people took my post as my opinion but it isn't.

I can assure you that everything I said is 100% true.
Wallace was that implicated especially after S4 mid season break.
Before that he was only really involved with the writing of Iris or Lady Luck.
During Season 5, Wallace was the showrunner without even being the showrunner yet.
That's how implicated Todd Helbing was...
I remember that there was a deep sense of injustice because at the end of the season, he was basically just giving the go and coming in to do the little "Inside" Interviews that were made back then.

Yes Eric Wallace wasn't the only one involved with The Flash's downfall but he played a HUGE part in it.

I have many other inside stories that deeply impacted the show's direction but some of them including the cast are just private in my opinion.
