So let's change the parameters slightly: instead of qualifying through Mountain Rage (which is a specific and narrow window, but isn't necessarily part of my question so much as it is the build that inspired it), let's say that this character qualifies for a level of War Hulk by wearing a continuous Ring of Enlarge Person to become Large all the way up to, and through, level-up... And then takes the ring off. What then? If he puts the ring back on, does he regain the class features that were lost prior?
The RAW answer is that you don't lose War Hulk class features by no longer qualifying for the class. If you want the nuances that go into why people commonly interpret it otherwise, then honestly, this question is enough for its own thread. It doesn't really fall into simple or RAW anymore.
