I've got a few questions on the optional regimental starting gear, nothing major. Hopefully some of it was resolved in questions in the beta or will be expanded upon in Hammer of the Emporer.
Firstly, with main weapon upgrades, as there doesn't seem to be a cost saving in buying a weapon as a replacement for a lighter main weapon was it not intended to be able to buy weapons with the any item of a given availablility option.
And not really bothered with extremes, rather than stocking up on several basic weapons or even a heavy weapon per man. Say you end up with a las pistol as your mainweapon (say because of the Warrior weapons doctrine), If you were still interested in keeping the pistol, would you need to replace the pistol with a lascarbine and then also buy a las-pistol as a sidearm.
Secondly, what's the cost of a single item per squad? Say a Vox caster or a few demo charges. Is the same as getting one per character? The only example of a per squad item is 6 screamers which I imagine is about the same as a one per character in many cases.
