It is way too easy now to be swamped by warp anomalies especially for a lower level character.  Either the anomaly spawn rate needs to be really toned down, the warp heat rejection rate increased, or the level of heat that triggers the anomalies raised. 

Agreed, it's gone from an interesting mechanic to play around to utter cancer if you even think of going above the minimum heat levels, maybe if the Res perk that prevents self damage stoped the problem as well, but as it stands it's just not worth it, frankly it's kinda making Psyker far less fun, I can understand the limit on self buffs but this on top of that seems like your just trying to stop people playing Psykers after all that work redoing the class
