Stetmann is of course infamous for lag, but I’ve never had too much trouble with it. Get paired with Stukov and sure, it would get bad, but besides that I’ve generally been ok playing Stetmann. Until I prestiged him. Now there’s noticable lag in nearly every large battle. The stetfields are bigger, plausibly covering more units, so I guess that could be the explanation.
Has anyone else experienced this?
Yes, also occurred during PTR as well.
The term is called Stetlag btw 
In the title bro.
Bugger. The large perm fields are so good.
Dang, I’m so blind 
Yeah, that was a big request for some.
Yep stetlag indeed, the prestige works and it is great, but as both you and ally creates more units, the game is constantly trying to keep the buff on your units, add that to healing and your unit abilities, especially zerglings, the frames will drop.
I only create a handfull of zerglings because of this, very unfortunate since stetmann is a strong, mutation-welcome commander.
Some time ago I noticed that even a small group of Zerglings causes a massive lag spike each time they start and stop moving in a Stetzone. My guess is that it has something to do with acceleration, and units constantly accelerating and decelerating as they push eachother and try to fit into an area. That, or pathing for this game was never meant to handle units above a certain speed.
Or my PC simply cannot handle the pathing for this game anymore… 
Its probably also because theres alot of traffic on their servers nowadays…
unfortunately i couldnt even play the system yet other than on ptr for a few matches…
but i guess theres alot more players around that all grind and try new stuff that may lag the servers (thinking of 103 Zeratul artifact game on DoN :D)
