So your suggestion to compensate for EF's terrible QoL issues is essentially "
group with less friends and guildies" in an MMO? Really?... ?
You missed the point. It's not about the difficulty or the challenge of the quest. Doesn't matter if it's a group of first lifers running Elite or a group of multipletionists running R10. It's about a one-off and completely unnecessary startup animation that is a significant detriment to the QoL of an otherwise great ability.
Sure, Fusilade is great for xbows, just like haste boost is great for melee. What's not great is half the mobs being dead before it activates because everyone else can activate their good stuff instantly. Also not great is EF getting interrupted and wasted after that startup penalty. This stuff is unnecessary.
