June 2017- What do you think of the new gym changes?
I do not play as part of a coordinated team so I do like the new gym limit of 6. Since the change, most of the gyms I've fought have been with 4-6 players and with the motivation vs prestige system you have to fight all gym occupants more (one does not drop after every round), but as their motivation drop their HP and general effectiveness drops drastically, so it's probably a wash, but it's described as needing 6 battles for even a single occupant, which on that level is more work.
Raids are not yet instituted, and if I have a concern, it's that this feature will make the game less solo friendly.
