Why did the Empire stop using the TK armor and switched to stormtrooper armor? Phase one clone trooper armor got phased out for the second phase due to it being uncomfortable, and then it was assumed that p2 phased out for a stormtrooper armor to distance them from the clones. But now we know there was the TK armor in between. Do we know why the TK armor was phased out?

Phase one was only in use for a couple years, but that was because of a design flaw. Stormtrooper armor was used for at least 15 years if not longer, it was used from at least solo until the Mandalorian. So it seems like when they have a good design they keep it. So what flaw do you think the TK armor Had that storm trooper armor fixed?
