Pokémon GO: 8 Important Fan Complaints Niantic Must Address

2. The 'Multiple Players At One Gym' Health Bar Glitch

File this under "Things you didn't know you could do", but if you approach a given Gym with friends, both/all of you can battle the defending Pokémon at once.

However, if you don't both start the battle at exactly the same time, whoever enters second/last will end up with a massive blow to their own Pokémon's health bar.

It can be assumed this is to ensure the attackers 'share' the same health allowance, but when you're entering a bout only seconds after your companion and being dealt blow that does 70%+ damage or knocks them out instantly, it doesn't add up.

Also, the game doesn't even tell you that group Gym battles are a thing. Any clarification on the rules and options open to us would be most grateful.
