No one ever mentions that most tankers run gunnlogis with double shield hardeners, and that the average player cannot on their own deal enough damage to one with a SL to destroy it. No one mentions that the only infantry held anti shield AV weapon is the plasma cannon.

K den.

But then again it's far easier for tanks to use terrain and buildings for cover.
At first thought it might feel the opposite, but it really is that way.

1st point depends on map and the terrain in question.
2nd point is not true: often swarm user launches with terrain close to him and only 1-3 missiles fly out. When that sole missiles hits, it is just that.

It is a sad fact from framerate performances perspective that all those 4 missiles are separate entities and calculated as such.

Nope, they are all separate.

1000% sure.

How often?
All the time, on occasion, sometimes, rarely?

If rarely or even sometimes the chances are there was combined volley.
I have the luxury of replaying my matches, so in every case of (near)instaboom I check them. Usually it was a well co-ordinated or lucky volleys by several ppl.

Using swarms alone it takes me 2 full clips of a proto SL on a double DMG modded min commando to take down your gunloggi (provided you don't missile me or run away or get out and shoot me/forge gun me)

Sorry to hear you're not indestructible, be grateful you don't use a Madrugar. Now HTFU.
