Firstly, congrats on finishing. Most fics on this site just get dropped halfway through, so it really is quite the accomplishment to bring one to completion. Now, that aside, it wasn't really a satisfying ending to me. Though I hate saying that since, as I said, most don't even get endings. So its a "be grateful you even have one" type of situation. It just feels like so much of what the MC did was ultimately... irrelevant. All the training and mastering different bending arts, surpassing limits, becoming an avatar, building a spirit squad, learning old and forgotten techniques.... in the end he is nothing but a baseline human fighter who gets lucky in a brawl with poison. None of the training in bending mattered. None of the effort in mastering different arts mattered. Being an Avatar didn't matter. He, essentially as a completely normal guy with some martial arts training, defeated the main enemy of the entire show - and died for it. It was just really anticlimatic. All that build up and in the end literally everything he has spent the last 100+ chapters building up and working for was snatched away on the whim of some god. I mean sure that is how it'd go too if messing with gods... but still, it isn't really a very rewarding or satisfying experience. Still, overall a good story and congrats again on finishing.
I think we missed out on a lot that was "teased" like poison bending and stuff and there were some frustrating things like this ending that kinda just skipped a lot of cool stuff (even the talk with Ravaa a chapter before the last one). I wasn't really a fan of him becoming an Avatar and would have loved to see him dominate with his unique water bending especially because the only real use that had was getting Vatuu (didn't really do much with most elements and even stopped using water that much). It's still a great read and I would enjoy more of it. I especially loved the romance part with Azula and how it was handled (not a big fan of romance/lemon stuff but the little that we got was done beautifully). All in all: 7/10 would read again.
