Except that is not really true not but for reason you think Liefeld has not been a regular on a book in ages I think Deathstroke or Deadpool corps has been the most books he has penciled in a row for long time(like 6 issues). Liefeld is rarely on series for long and most cases he has another penciler drawing. I keep on saying they are legit reason to dislike and criticize Liefeld and people don't have to make up stuff. It hard to say interest wanes like he has track record for staying on book for a long time he mostly does an issue or two . Even when he was in "his prime" he didn't deliver books on time so you can rarely find long stretches with him.
On that note Whilce Portacio and Brent Peeples are doing issues 2-5. So literally people are complaining about Liefeld drawing TWO comics of a mini series that is even necessarily continuity and it is pretty much ignorable if Marvel wants it to be that way.
