The lore of the cards is meant to give knowledge of the game not dictate what guns players use.

Yes, but it also contradicts itself, regardless of its use. The idea of Gally being just for Titans is actually pretty cool, so long as all the other classes had their own one-off weapon equally worthy of use.

Yes but can you imagine all the complaints/ outrage if gjally could only be used by tits?

Not if it was like what I said, and Warlocks and Hunters both also had a weapon of incredible use just to themselves. Would actually promote people working together better, or so I'd think. So like... if Titans had Gally, Hunters had let's call it the Invisible Spear (I don't know... lol) and Warlocks had the Sun Raker (still don't have a good idea for a name) So if all 3 had a different class-exclusive weapon with ridiculously powerful perks, I'd be completely behind that. Let alone the fact that it might actually encourage people to play as all 3 classes.

Nah the weapons are forged in legend for all guardians to use. The game would be beyond broken with character exclusive weapons. Besides which we already have that with the subclasses and special moves. The logistics of putting together a raid squad would be horrific if you needed specific weapons on characters. Just no.
