PD and City Defence bonus

It pains me to say this but PD is becoming a little bit boring and in games I feel is way above for a strategy pick.

Simple solution make city defence only +1 like other strategies. It will still retain its advantage over tanks and with upgrades still be very very tough to break. anyway just my thoughts.

Pd has remain the same for a long time, why change something that not even op. we can't just change everything because its popular or not. instead of nerfing stuff, why not buff other strats.

I completely agree that other strategies need a boost, nonetheless imo PD in smaller battlefields is the most effective. With all infantry upgrades statistically you are getting a lot for your cash and spawn. Late game play with good players is focusing around attrition and nothing is better for that than PD. I'm not proposing a strategy breaking nerf here.

PD is effective the way it is... unfortunately; don't like Inf spawning.

Other strategies need a boost rather than PD getting a nerf. Also, I notice that there are a greater number of infantry upgrades than tank upgrades by far. Why not give tanks similar upgrades that infantry have so that tank based strategies will be just as attractive as infantry ones like PD? Just a suggestion.
