Some of these changes are really extreme.

TOW

The tow was only a problem for lower PS matches and now it's useless for everyone. At first I thought that the faster reload time maintained its viability, but after several more matches-I realized I was wrong. It's just not viable at all.

All one needs to do is make a small turn to avoid it as the missiles turn rate is so slow now that it can't change directions quickly enough.

On the opposite end of the spectrum..I no longer even try to avoid them as they deal so little damage that they can be shrugged off. Case in point, someone tried using them against me. 4 missiles later, I still had around 1.7k hp left, from 2.1k.

Tow is now little more than a guided camera.

Sidekick

As far as I can tell, sidekicks now roughly have the damage output of reapers and perhaps higher.

Shotguns

The issue with shotguns is not their structure. It's their size. A structure nerf will do little to nothing as they can so easily be protected.
