To add to my thoughts, even before the current season it seemed the vast majority of psyker builds are built for low heat, and the update doesn't really affect their potency too much even now. High heat has always seemed to be a more niche thing. 

The update nukes a mostly niche category of builds into the ground. The current season has seen cooldown reductions greatly nerfed, alongside more frequent anomaly spawns with a greater variety at high heat. Perks central to the high heat build, like Reverse Warp Attenuation is also nearly useless in comparison to the Psy Focus tree, due to how negigible its health gain is. Paired with the Precognition nerf, all the jank that comes with warp anomalies can't really be negated, and so playing high heat psyker is now very unpleasant. As someone who has spent several months grinding to perfect their psyker build, this season's psyker changes just aren't for me, sorry.

I kind of agree as well. The new update killed high heat builds due to the sheer amount of jank that warp anomalies suffer from.  Anomalies have a nasty habit of blending in to the visual clutter of  levels, and paired with how punishing they are (the triangle tends to clip into terrain, and inflicts a slow status while the chaos mark is extremely hard to see in many circumstances and completely removes suppression), it tends to be very unpleasant to play as one. I don't believe azot is wrong in this instance, as anomalies can definitely do with another look.
