I don't think stalkers are in the same category as blasters for damage OR cc.
Blasters do a whole lot more overall damage. And has access to either a lot more damage, or much better controls than the stalker.
The stalker of course a lot tougher. And does great against hard targets.
But my billion influence stalker build can't hold a candle to my barely built fire blaster when it comes to most flying orange numbers spamming my field of view.
