I think the repair option is another amusing/annoying trope.
Of course, this is a fantasy RPG, but still....
A suit of plate is a costly, difficult item to make, and in fact, it has to be made specificly for the wearer. It takes a long time and a lot of skill. So why is in FRPGs it can be done in twenty minutes? And why is it, it can be repaired in the middle of nowhere, with no anvil, no furnace and what have we?
It's as silly as crafting where you mine the raw-materials yourself, smelt them, cast them to ingots, smith the ingots to whatever item, temper it, sharpen it, and put on hilt/handle. All by yourself.
Stop it already! That's why there's MONEY in the game. So the protagonist can pay craftsmen to do craftsmens work.
