The trick to complexity is to not think of it as a trick. To the point of @bdramby, I wouldn’t even think of it as an unattainable point, but more a holistic one: do you carry your argument throughout?
The complexity point starts with a complex thesis, and it’s typically a cascade point (meaning, you’ll rarely earn it if you’re not earning the majority - usually all - of the other points). I agree that it’s not the first point to shoot for, but if you’re writing well, and your argument is founded on a thesis that’s ARG + WHY + COUNTERCLAIM (however/specifically/etc), you’re on the right track.
*Asian responses to imperialism typically included some sort of reform effort. However, more often than not, resistance permeated Asian responses to European imperialism due to the desire to maintain cultural boundaries in the face of threat.
^ If your body paragraphs don’t singularly focus on ONLY reform and resistance, but instead weave them together - that’s complexity. The Ottoman Tanzimat Reforms might be an example here, where they attempted to modernize somewhat (reform) but also demonstrated significant resistance, both to imperialism and internally in the empire.
