I ban LRMK 'cos, what I've heard confirms that.
Also I've had one hell of an engagement in Battlefleet Gothic Armada.
When playing campaign, there is a chance of a "Nemesis" enemy attacking a system. These are fleets led by infamous flagships, each of them dedicated to each Chaos God:
Khorne - Eternity Of Pain, Desolator Class
Slaanesh - Torment, Desolator Class
Nurgle - Terminus Est, Despoiler Class
Tzeentch - Sword Of Sacrilege, Despoiler Class
And, one turn, Sword Of Sacrilege pops up for a Data Recovery mission, so I had to get close to that freaking battleship and board it. So I grabbed my own battleship (Retribution Class) and 3 cruisers (Lunar, Gothic and Dictator) and decided to drown the freak in torps. In retrospect, a bad idea due to the amount of fighters Despoiler can pump out, but it worked - several torpedo salvos, macrocannon salvos and one ramming attack by another battleship and Sword Of Sacrilege turns into a smoldering wreck.
Ironically, the mission was failed. While data was already aboard my battleship, a Hellbringer Light Cruiser boarded it, popped shield (preventing Lightning Strikes) and warped out with the data before Loonier Triplets could do anything about it.. To think about it, that was so Tzeentchian.
More irony - both my first battleship and first battleship kill ended up to be Despoiler Class with Tzeentch dedication.
