As a new player - I'm just learning the game, so I apologize if I'm not quite getting this system. If I can work up my skill enough to craft a low-level set of armor, as a low-level, level 5, I should at least be able to wear it. What is the point of having a set of low level armor that you cant wear at low levels? Pretty much any game will let you use a full set of low-level armor at level 1 - assuming you can find/make it all. If you don't want to allow players to wear full armor sets at lower levels, then lock all armor slots until a certain level, then add slots as you level. It would still provide the same progression you seem to want, without confusion for new players. Limitations without explanation tends to turn players off.One of the things we wanted to do when designing our armor system is provide as much flexibility to the player as possible. This mean not adding role restrictions to armor, but instead trying to find another way to restrict what people could wear based on their role. This is where the armor weight system comes into play. Each slot has a fixed armor weight range for equipped items. Each role has an armor weight allowance that when exceeded imposes pretty strict penalties. Ideally this would lead to visual variety, but also some difficult decisions you as a player have to make about what to equip, and what to not equip. The system is a bit unorthodox yes, but we also feel that it grants the player a great deal of flexibility in the armor that they wear.
We also recognize that we are fighting an uphill battle in a way. Traditional MMOs have trained players to "fill every slot" if they have the equipment to do so. We are going against the grain here and allowing you to pick and choose which slots to fill as you level up (you unlock more armor weight as you level).
