Default unit selection in the group (PTR)

Is it a bug or feature that the Overseer is the main unit in the group now?
I’m not sure what is the point of having it as a main unit since there are much more important units to control, especially since Hydra has that new dash ability.
Also i don’t understand why they made Lurker higher tier than Roach + Hydra for example? I can have them on the separate group to burrow. I would rather control the Ravagers. In general there is much more logic to have default selected unit’s like those which has some fast regenerating ability like corrosive bile etc.

dude, seperate your stuff into different control groups. not understanding why your here complaining about anything right now. do you even know how to play this game.

Do you even make lurkers? They’re one of the clunkiest units in the game, the fact they have top priority is a great thing. Ravagers should be the ones on your control group anyway as they are a spell caster.

I think queens should be lowest. I have bad Habbet scroll my mouse on army to defend dumb queens gets yanked. Tab to ravagers it’s slight annoying.
