Infiltrate is the outlier for me.
Only really useful for Objectives and picking up players, which has its uses but usually a grenade explsion can accomplish the same task if an Ogryn isnt already doing that job while you cover him.
Infiltrate could use a rework. I think a turret could be in order or something to push this class to a support role…
Its tough to diagnose since most casuals want the traditional fps pew pew CoDman playstyle.
This could work, turn the vet into a Catachan .. or Tempestus Aquilons
Give a high skill ceiling glass cannon.. an ability to float just above Ogryns head to stay out of trash melee range and get the job done from above.
and according to the datasheet, they should get sentries..
I think this would be awesome and add a ton of utility to the vet.
