After qsynching in a factional with three other people to test swarms (myself, Halla Murr/Kallas Hallytyr, Shotty Gobang/Adipem nothi, and Jaceon Pale Eye), we have returned with conclusive results on the subject of swarms vs ADS:

Results found:

In our match, we had found a giant spire and a mountain to test the homing and acceleration of swarms vs my ADS.

We had first tried some evasive moves around the spire to see what could successfully make the swarms collide with the spire.

Keep in mind that each tactic used had two volleys of swarms going after it
Also keep in mind that the numbers I use are guesstimates, but should be close enough to the real number
One more thing, keep in mind that these are the results from my point of view, I was not the swarmer, so I cannot offer his POV.

First move was to fly around and stick close to the spire starting from the left side of spire:

1st volley fired about 15-35 meters before I was to make the turn

2nd volley was fired about 1-3 seconds before I made the turn into the spire:

Results: 1st volley had confirmed to veer about 1 or 2 missiles into the building, rest connected to dropship. 2nd volley collided with building as I was already around the other side when they had reached optimal acceleration.

Second evasive maneuver:

I had attempted to fly an upwards circle around the building starting from the left side of spire

The volleys were assumed to be fired at the same intervals as before.

1st volley had hit me with 2 or 3 missiles while I was making my way around the spire and about to do my upward twist.

2nd volley went all "Byatch please" on me when I reached front of spire and hit me full force.

Third and I believe final evasive maneuver involved flying around the left side of the spire and continuing flying, but on the right side of spire after passing spire:

1st volley hit I think with full force, 2nd were no different on the results.

We also tried to simulate an ADS using the mountainous terrain and avoiding swarm fire:

In order for you to get a full understanding of this, I'll have to explain to you the terrain:

There were two flat lands separated by a mountain: left side was more elevated than the right side, and swarmer was positioned on left where it was more elevated, hill was about 2 feet high (could be wrong)

The idea was for me to fly as low as I could starting from the left side, which was more elevated than the right, by about 5 or 6 feet and continue flying as low as possible while on the other side of the hill.

I'm afraid we didn't have enough time to double check these results, but here's what we could get.

1st volley was fired after I had past swarmer Adipem, about 20-30 meters before I had hit the slope to go under.

2nd volley was confirmed to have been launched barely before I had gone down the slope:

Results:

1st volley had hit me about 30-45 meters after I had gone past the slope and still flying quite low. All four shots had registered

2nd volley completely hit the small hill as they were already fired barely before I had gone down the hill.

Opinion: I believe that in an open engagement with swarms, they have the clear cut advantage, as the first volley had hit me full force AFTER I had reached past the hill and flew low.

I believe a slight homing or acceleration nerf would do well for the balance, especially in the wide open spaces, it would help those good enough to fly low to avoid the missiles.

Anyway, these are your results, take them as you will.
