Does anyone else feel that Ammo Pools for certain weapons are inappropriate sizes?

My main source of this feeling is my Vanguard and some of the weapons on the Sundy. For my Vanguard, I feel like 30 shots by default is far too few. While It's true that I rarely ever manage to fire them all, I've always attributed that to me being a less than stellar tank driver. Whilst other weapons (Such as the Sunderers Basilisk) have ammo pools that have me feeling as though I could hit one shot in ten and still never fear running shy. I was curious if I were the only one to feel this way, and if not, if anyone else agreed that perhaps some adjustment would be in order?

Heavy vehicles tend to carry less ammo to force their reliance on supply lines and limit constant farming by forcing the vehicle to eventually return to base and get more ammo.
