I'm a mobile player, and what annoys me the most is being pvp against a player and, unintentionally, ending up opening a chest in the middle of the fight, because for those who don't know, the cell phone doesn't have a button to hit and another to open chests, on mobile you can only click with your finger and nothing else. My suggestion is to make the chests can't be opened with a sword (like the villagers who sell items on EggWars), as this will facilitate the pvp for mobile players and won't hurt at all for players on other devices.
