@Kolysycol,

PLD main here, and one who also loves using Clemency in dungeons. As for the reason why I do this, I personally just really dislike falling below 80ish % hp. No matter what game I play, I always just like having lots of HP. Also, I don't like completely relying on somebody else to take care of me in this regard. Clemency is an incredible powerful tool, so I will use it.

I'll be honest Kolsykol, if a healer told me what you tell other PLDs in dungeons, I'd be annoyed too. Definitely not excusing PLDs cussing you out or things of that nature, but I do think their irritation is justified. You claim that you're not trying to tell people how to play...so why even try to confront someone about this? It's not about not trusting you, personally, I just like to take care of myself as much as possible. Especially when I have the tools to do it. A PLD who wants to heal themselves isn't bringing any real harm to the group, in fact, they may be saving you some MP. If someone is doing something that isn't truly hurting you, don't try to make them feel wrong for doing it.

I won't speak for others, but for me, if someone does this it makes me feel like they think they're some all-knowing higher up (which they never are) who has the right to pass judgment on everybody. I don't like that, at all. A, because like I said it's not true, and B, because it's kind of rude and jusy flat out annoying, no matter how "polite" you try and make it sound. Rule of thumb: unless someone is obviously ruining the group and stopping you from progressing, just try not to say anything.
