That’s the thing, ppl don’t realize that Swann is the “Terran Turtle Commander”. The turtle formation consists of bunkers, tanks, and supply depots/barracks. Turrets and Factories theme substitution. He can (re)erect a turtle formation in short time with the Herc to deploy the Tank part.
I think…
The original intent of Swann play was reward turtle play style. He’s given the Drill and the Herc to enable assault support. Hey, this is “CO OP” right? This enables the ally to concentrate mostly on spearheading the assault while you can rely on Swann to protect the base.
That said, even with all the “offense/rampup buffs” they’ve given Swann to make him more “popular”, he still excels most when this strat is the optimal way to beat the game. So maybe he isn’t great at Lock and Load in 5 minute runs. But if it’s hard enough (or you aren’t good enough) that you need to do it patiently and actually DEFEND and perhaps retake the locks, he really shines.
