Why does Psykers have the Strength aptitude? Am I missing some kind of build where this could be good for the psyker? A melee Psyker seems impossible to run in Only war, given that there are very few powers that work with that and that Force weapons are more or less impossible to get hold of. Or is it just lazy designing, and giving the psyker a pointless aptitude to avoid making him overpowered by actually giving him a meaningful aptitude?
If I were to houserule this what would be a reasonable aptitude to give the psyker?
The talent Resistance (Psychic technique) is more or less a must for the Psyker to buy, since it's required to get most of the useful psyker talents. But the psyker has no matching attributes and the talent is thus quite expensive (ok, it's only a tier 1 talent so it's not that bad). Toughness should not be one of the aptitudes for that particular sub-talent in my opinion, instead replaced by Psyker or Willpower.
