Anyone else think some gyms should have special conditions?

It'd be cool to have gyms specialized in a certain type alongside the "generalist" ones, a bit like the original games! So that you can only put Fire types to a Fire gym, and so on. I think it would make a lot of mons more useful and add some variety to the current meta. And it'd be fun.

I would like a gym without gps spoofers

At first I digged the "1 type" only gyms like the original gyms that gave out badges. But Ash never had to battle with only that type. So restricting a Gym to only having 1 in it, would just make the gym easier to tear down and harder to put up

Now maybe if existing Gyms got an "add to speciality Gym" which would be same rank as main gym but with same rule. And you couldn't knock out people in specality gym only main one. So it would entirely be for xp and maybe a reward for beating the sub-gym.

In fact thinking about it, the Sub Gyms being 1 type only with a CP range. Would be very interesting because people might try extra to take over say a Gym where they had pokemon that fit into the main gym sub gym.

I wouldn't mind additional special single type gyms.

I'd like main gyms to be one of a species only.

In general though I don't want the game to get over complicated.

If something like this is ever implemented, instead of straight restricting types, it should provide a bonus to pokemon and/or moves of a certain type similar to the stadium cards in the pokemon TCG.

i.e.:
Lava Gym - Fire pokemon have 125% attack. (This would cause CPs to recalculate so matching pokemon would place a higher also.)
Sea Breeze Gym - Electric pokemon have 80% attack. (Helps both water and flying.)
Floral Gym - Grass pokemon have 125% HP.
Thunder Gym - Electric type attacks have 80% duration.

Then every two weeks or so when nests rotate, the gym rules could also shift so players if different areas can experience different gyms.
