This is a limitation of the game unfortunately. You can only arm 1 of any item on your person, however anything you don't have armed on yourself can be taken into battle by your Mob which is useful for general PvP.
Kano should have let new players know that before they sell the items. Would have bought a vechicle instead of 2 armours.
The game still uses the item when you are playing, ya not losing anything, I know people that buy multiple limited items, big spenders do it all the time, they but 5 to 10 to whatever of the same items.
Your loadout isn't that important in LCN, you use all of your strongest items for fights whether or not they are in your loadout.
Really? I know you can have attack, defense, and overall best loadouts, but I didn't think it made a significant difference except for arenas and wars. I do know that disabling elites and having no loadout can make a difference for leveling partners, but I don't do that myself.
I mentioned the arenas and wars, Wrecks. But loadouts are useless for bosses and practically useless for fights unless you go with no loadout, right? At least after you've been playing for 5 years or so.
