So it's been a bit since this part of the story occurred but I never have placed my thoughts somewhere so felt I should here. Essentially you lose twice to Zenos, although without much drama compared to WoL's other 'final battles', which I find odd but that's a whole other subject so I'd like to focus on a different part that urks me to no end.
With the previous two battles the story wants to imply that Zenos is much stronger than you and even with the second battle you really don't do much anything at all to him and still lose.
Yet... on the third confrontation, you actually beat him then he fuses with Shinryu and you beat that too? The heck??? So you're telling me someone who eclipsed us in battle strength the previous two fights we were able to not only transcend his base form but a form with him and Shinryu as one?
It's completely unbelievable from a narrative standpoint and really damages the whole dynamic they laid out here in my opinion.
