.oO(trollmeat has strong opinions about massive weapons)
So, um,.. about the Basic Weapons + Massive Weapon...
It is a great combo because you can carry a Basic and still get all the strength and charge bonuses of the Massive Weapon, but the Drawback is the Draws. As the rules stand, it is no more ponderous and clumsy to carry only as Massive Weapon than it is to carry one as well as slinging a basic weapon over your shoulder.
This works quite well fluff-wise, and the rules of how awkward it is are fine as is. If the only firearm options for a dude with a massive weapon was from the pistols range, then it would not be worth taking it at all.
+ The hidden bonus for buying a pistol is that, even if you buy no other pistols/cc weapons, you get +1A as long as you don't buy a Basic+.
- The hidden negative for buying a basic is that, no matter how many pistols and cc weapons you buy, you can't get +1A.
~ using a massive weapon means you can't get +1A, no matter what other weapons you carry.
= Massive Weapons are a great option for Heavies, especially if they have advanced with +1A, or for anyone shooty that wants to discourage people from charging in...
