I sat down this morning to write up a couple of characters, testing out the latest update changes. My Hive World Outcast Warrior spent 600 (!) of his starting exp on Weapon Training (Low Tech) and Weapon Training (Heavy). Seriously, 2/3 of his starting experience was spent on two Weapon Trainings... one of which involves being able to use a knife. This is ridiculous.
IMO, all Acolytes should start with Weapon Training (Low Tech, Las and Solid Projectile). In this way, they all start with the ability to use the most common weapons of the Imperium... which only makes sense of agents of the secret police of a universally militarized culture.
Under this model, characters would have to pay experience points for access to the more powerful "special" weapons... like bolters and chainswords, plasma guns and power fists. This puts a mechanical limitation on those weapons beyond just getting ahold of them and is why I prefer this model to simply doing away with Weapon Training altogether.
