i have friends with static group that not received EVEN 1 PIECE of ALLAGAN(legacy players) the chance is very low.. you know that
Everyone gets the same "low" chance. it's not like it favors one person over another. The chance is supposed to be low. This is supposed to be less common gear than the usual dungeons.THIS IS NOT WP or some sub lv50 dungeon.

It's just your bad luck if you have competition, you are within your power not to party with someone else being on the same job in the party (I wouldn't take 2 DRGs or even 2 melee DPS in most turns, especially t2)

Honestly, I'm thankful that there are 2 drops in each turn boss 100% of the time. They could have made it like 1 item with a low drop rate or something like they did a lot in FFXI. If you played FFXI, you would know just how much more common this gear is than the best gear in XI, especially in its heyday.
