On armors, magic could make the armor feel lighter than it should, and/or increase the strenght of the wearer, thus allowing more agility and speed then normal.

However, the biggest downside to plate armor, is not the weight, but its movement restriction. If wearing a helmet, your field of view is greatly hindered, and the plate itself is hard to move in. You can't lift your arm as far as usual, or move your legs around as easily ect.

That sight hinderince is a huge thing to Cody actually, his magic pretty much depends on his field of vision (it's the major factor, there are a few minors ones which also have a big influence).
In fact movement constriction was something Cody wanted to avoid as well, another big factor of his magic is reflex/reaction speed and movement speed. So plate armor was pretty much always out of the equation. (The other factors are pretty much time, distance, magical power
So that was probably a factor in [@Zarkun] choosing chainmail. Also Cody still has a largish sum of jewels from his foster parents before their death (he was in a rich family you know) and taking odd jobs, so price isn't a huge factor (as long as it doesn't cost like a 1,000,000,000 jewels or something stupid XD).
