I thought they said it doesn't matter which one you join. So, maybe they will make the reward similar. But now For example:
Lominsan Lance Unique Untradable Lancer's Arm
Damage: 143 Delay: 3.7
Attack Power: +25
Crit Rate: +15

Gridanian Harpoon Unique Untradable Lancer's Armr
Damage: 125 Delay: 3.3
Accuracy: +25
Parry: +15

Ul'dahn Guisarme Unique Untradable Lancer's Arm
Damage: 140 Delay: 3.7
Accuracy: +15 Attack Power: +25

well if you look at the LL's stat it's not bad compare to ifrit. but what's that Grid one DMG 125? Even Hart Guisarme is better than that. And Parry +15!? /passout

Lancer guild at Grid too.
Rabble rabble rabble!
