Ok, there's a thread on (ugh) rpg.net that compares the DH2 rules to flaming horse garbage.
Here 's the link:
https://forum.rpg.net/showthread.php?740583-Dark-Heresy-2nd-edition-s-rules-are-also-a-flaming-pile-of-horse-garbage-Edit-Not-that-bad-but-****
Basically, the Op, who is generally abusive and bullies people with his mod power, in addition to taking pride in writing viciously hateful reviews of games he doesn't like, is complaining his whole party was wiped out by one psyker roll in the intro adventure, then makes it clear he did not understand the game rules which technically said his party wasn't killed and there were ways he could have avoided it.
he decided not to spent a fate point to avoid a perils of the warp roll, for example.
His group did not understand that zero HP does not equal death in DH2.
His group did not spend fate poitnts to survive the blast.
And lastly, most easily, when a psyker starts to use a power the rest of his group could have just stepped away from him quickly,. which would be a very in character thing to do. But no, they played DH2 like it was DnD where having a wizard use magic is no big deal, they did not understand the 40k setting where psykers are barely tolerated as a necessary evil and even at best are rightfully regarded with fear, distrust and often loathing, they played him like a wizard in DnD. If the party had stepped away from the psyker, no TPK. If they'd spent fate, no TPK. If Maclennan had spent fate, maybe no TPK.
Also, since it was a 2d10 explosion ignoring armor, killing an entire party of uninjured characters with fate to spend should have been impossible if they'd known the rules and used them. Just going to zero is not death in DH2.
I can't post on rpg.net but maybe someone here could go explain to Mr. SJW that if he had played right there'd have been no TPK, and if his other players had acted properly there'd have been no TPK. Just be prepared to be banned for saying those things are the OP over there is notorious for abusing his mod power and taking any fair rebuttal that effectively debunks his points as asking for a ban under rule 10.
I sympathize, but that is a very old thread now and its not like it can do anymore damage as Dark Heresy is officially dead (not that it will stop current players such as myself from playing)!.
