When new gears arrives, Release an NPC or something that allows players to use the new gear for a certain period of time, in order to test it in dungeons . The time shouldn't be so long of course, but should be enough to try it out and it cannot be used in lb dungeons.
It would grab more feedback to devs and help players to decide if it's something that worth buy or not.
The primary idea would be to have a training camp, where u could choose the gear u want to use(The options could be latest/most popular gears/arcanes/myth) but maybe it would require alot more efforts to be done than the first suggestion.
