Please bring back /chest in combat, it was a vital part of pvp so you can carry more sets on you, and you dont break or lose all your armor in a 1v1. Also, if your in combat and you need to grab more gaps or potions, /chest was the best/quickest way to do so.
If you were ever able to use /chest in combat, it was an unintentional oversight that should have been fixed sooner.
Just grab what you need before you pvp, like 3 strength pots and gapples etc and like 6 sets of armor
Having /chest in PvP was a problem. People would do 1v1s and have their /chest full of armor and gapps. /chest is meant to store items, not to be used for PvP purposes. Disabling it in combat was a good idea. Kudos to you Staff!
