In an interview with Polygon at GDC, Pokémon GO developer Niantic Labs have admitted to the fact that gym battles need changing in their widely popular mobile franchise.

Speaking to Polygon the developer said, "The gym portion [of Pokémon Go] needs a lot more work, and we are trying to improve it and make a bigger change to how the system works. Overall, I think we need a little bit more time to think through how we do it.”

Among other things, the developer also talked about instituting a trading system in the game, as well the recent introduction of Pokémon a few weeks ago.

When Pokémon GO was launched last summer we said, "Pokémon GO might be one of the coolest, most socially constructive games ever,"  and the addition of new gym battles might be a worthwhile step in accomplishing this goal.
