Fairy meter, while not the most desired resource, is also not accumulated while the fairy is away even if you use the extra aether charges.
Thus in practice using it to buff a crit shield before deploy is typically its primary purpose, because otherwise its benefit only shows if you're actually having to spam-GCD heal a tank with adlo and physick, and even then it's very situational for the 20% healing buff to prove better than having the fairy out to embrace, and not at all better if Seraph's cooldown is available. And that's largely it. There is always the potential to pop it in an "OH CRAP" moment where triple lustrate may give you a clinch super-save, because those moments happen, but those are its role, and the cost of using it remains awkward and annoying.
That's not to say it isn't useful, because Dissipation was always great to have at the end of damage-AoE-spam phases like Brute Justice's fire spin, Omega's final phase, and Ultima's last charge attack. It's always been great for beefing up Succor at the tail end of a fight, but more often than not its primary use was additional energy drains, and with that gone, it's just become even more niche due to its weaknesses.
