Does which character you play affect weapons drops in Mass Effect Multiplayer?

Solution 1:

No, the items you get out of the various packs that are available is dependent on the pack you're purchasing. Within each level of pack you will get a specified chance at various items, in the higher packs you also get the opportunity to get Rare and Ultra Rare items. The drop rates per pack are detailed in this question.

Keep in mind that weapons have a maximum level - once you get them to level 10 you'll stop seeing them appear in the packs!

I have only included the rarity name (ie: common) in the tables below for space purposes. For the rarity of each weapon, look at this list:
