I don't see why magstrike isn't on top tier... requires no modification to be used like a B0SS. ...The magstrike also has an incredibly low jamming ratio, and can be reloaded on the spot if you are the proud owner of extra clips...
All excellent points, especially the no-mod one.
...the fastest firing rate of any blaster.
Which can be a liability. Very rarely do you need 900RPM (gen 3) or 600-750RPM (standard) for anything. And without custom 20 round clips (modding) you are in very serious danger if you need to engage anything more than a single threat in an emergency scenario (this may be a lot different if you are skirmishing or engaging a target you are well aware of beforehand).
Its compact... swarms require all those batteries.
Batteries which can be placed anywhere, and are about a quarter the size of the MS's extra bulk compared to a swarmpistol in the worst case (lots of big Ni-cd cells). In the better case (14500 or a small Li-po setup) the batteries could conceivably be mounted on the gun without a significant change in bulk.
And as someone who uses a swarmpistol I can say that no, a MS is not more compact. Unless you are using lead-acid batteries and a shell on the swarmy, it won't ever be as physically big as a MS with the bladder housing mounted nor as unwieldy to use holstered. There was a pro MS operator here a while back and he used (IIRC) a messenger bag with the MS and some socks stuffed in, and the bladder housing stuck out.
Vulcans require new motors
That is not so. I know that all everyone remembers from my Elite Vulcan build post was that huge motor, but in all reality you only need a motor swap when you want 500RPM or more on a beefier spring than the OMW 2.0, which is about 1% of vulcan builds. Stock 360s are good to get 600RPM out of a stock spring or 500 out of a 2.0 before voltage starts getting excessive.
Additionally, vulcans and magstrikes are as apples/oranges as you could get about automatic weapons and I don't know why the vulcan was mentioned in a secondary thread, unless that was just about dakka factor.
