From someone who really liked Age of Calamity, the one based on Breath of the Wild, if you haven't yet, play that one rather than Age of Imprisonment. Age of Imprisonment is just not as fun.
Most of its characters feel bland, unlike the crazy movesets and unexpected characters from AoC. This time they had to create a lot of new characters while the first one had them already established, but the new ones are mostly uninspired.
While AoC had slate powers that were interpreted differently for all characters, AoI replaces that with the Zonai artefacts that work the same for everyone. There are also individual powers that are slightly different, but they use the same slots as the artefacts, and unlike them they have long cooldowns, so you end up equipping the convenient but boring gizmos instead.
And the worst part, the game never challenges you. There are very tight battles in AoC having you running through the map and using a bit of strategic planning, and messy but exciting fights against several dangerous enemies at once. This never happens in AoI, it's mostly routine.
