[Lotm V3]At what volume should I stop

I started reading lotm a 2 weeks ago,got hooked,and eventually joined the sub,I've heard that the ending was rushed,it was trash,the author should have done better,etc,etc.This is the 10th novel I've read and I like to read things until the end,but with so much people saying that the ending is bad,I'd like to know when to stop,or at least when the drop-off starts
