Complaint about NIN from a Healer:

[Mhaeric]

It looks too much like Doom, and in fact the words "Doton" and "Doom" look rather similar at a quick glance, and sometimes when NINs use Doton, it sends me into a split second of panic of trying to heal a NIN that doesn't need healed because I mistake "Doton" for "Doom", esp when I've yet to realize we have a NIN in the DPS, if I'm not expecting it.

But you should always be expecting Doom. It only ever occurs in specific content and is always scripted.
