Overall in the group? Yes, but that is negated by the fact that they share the loot list.
Even if you had the drop rate of one person's personal loot list's 10% chance of any weapon (roughly the same as Darkhold, which was out just as long as Ifrit.), people could get loot just as quick but organized linkshells and groups could actually distribute drops and get their members the gear they actually wanted faster.
"Oh I'm sure they took everything into account and made this awesome loot system as the best possible solution" have you even done Ifrit?
People obviously wouldn't be stopped from doing content if the drop rate was <2% (been doing it for a decade) for the weapon they want, as we have tried to hammer into your head for the last 23 pages and multiple threads we just want to be able to get rewards as a group for group content.
