Quote from Fracture;1231656:
For the most part, all Light Armour sets are equal except for the Languris Chaser set, which is waaaay end-game gear. Your best bet is to just pick up some light armour that has been tailored by someone to have extra def/prot. As for Heavy Armour, if you don't mind grinding, the Royal Knight stuff you can buy from the seal shop is really good. Otherwise, use a well-smithed Plate Mail or something for some PD while keeping to reasonable maintenance costs.
Pretty much sums it up really well, also another armor that you might consider would be Chinese Dragon Armor for the speed effect if you plan on using anything besides fighter and puppets. If for just fighter and puppet then really I don't see a reason why you would even want the languhiris armor. Any chincey armor would work well enough preferably something with really high durability like the Lorica Segmentata. And imo the only two heavy armors worth getting are royal knight armor or thames set.
