i believe gw2 has got this right (dont quote me on that)... but i know wow and warhammer online needed an addon to do this. important to have a way to make 'gear sets' so we can switch our gear around easily without having to pull up the paper doll and inventory and screw about for 10 minutes trying to find what boots go with what gun... etc. any decent player changes sets dependant on there role in specific situations. tanks set? deeps? hybrid? bolters? melee time?
Yes - you'll be able to create different sets and load them quickly without going to your inventory/character sheet.
