The main issue is that the BB itself does not scale in any way (execpt warp charges but in this instance that doesnt really count) from lower diffs to higher. I can and will oneshot the flamer enemies and the grenadiers on Malice (3rd diff) but as soon as i go to Heresy then i can no longer do what i was able/am suppose to do on lower diffs such as kill high priority targets like the flamer and grenadier. There are more chances your BB gets canceled as well from the increase in enemies and therefore attacks, so your odds of getting a warp charge is worse (as it just isnt going to kill things because they have more hp) which leads to your whole kit being less effective as well. And yes the sharpshooter has a similar task/priorities but when such a large part of Psyker’s kit is related to BBs -which keep in mind dont scale- leaves you out to dry when you want to be effective on higher diffs like Heresy or Damnation. Whereas the Sharpshooter has their kit scaling because it is based of the weapon you use so it can be more effective at the higher diffs. This leaves Psyker in a spot where from what i understand is it cant do its job like it is suppose to and so you become an “anchor” weighing down your team so to speak. I dont think that BB should just be free to instakill every special and elite in the game but when a core part of the character just doesnt shape up when you go to the higher diffs then it feels bad to play and unrewarding.
TLDR: BB needs a little love/scaling for the higher difficulties
I did test the bit about the flamer enemies comparing diffs 3 and 4 but i didnt test on diff 5.
As well as not testing the Grenadier at all really, that was to use as an example of a special enemy that you would be trying to BB. And im not going to be testing that myself as im not playing (or launching) the game after the recent responses from Fatshark.
