I can't say I'm the best player ever, but I know enough to not get myself killed. So, as a healer, it's just fun to go around reviving people, helping new comers out, and explaining mechanics.
And it tears me so when you can tell people are having a hard time and quit out of a duty. Like, no...come back, I won't judge you. One DF I was doing Titan NM leveling up my DRK and healer was like, out-of-the-boat-to-a-new country-new.
She would keep healing in Cleric stance and so we told her not to as it would drastically reduce her healing capabilities- and she didn't do anymore so we got further that time.
But she couldn't dodge and I really couldn't explain that mechanic as it's too self-explanatory. She kept getting punted off the edge of the arena and she kept apologizing like literally kept apologizing.
I kept reassuring her that we can kept trying "'cause it's no use to anyone else if we vote abandon and you go into another party with less nice people".
Others joined in to and reassure her we can stay until she got better with this fight.
We explained to her that the fight is basically a wake up call and that she's gonna face other instances that will be ten times tougher than this fight if she's to continue playing.
She thanked us and we continued...but she kept getting punted off the edge. At that point, there was still nothing left to say, so I kept quite.
Then all of a sudden, she left. We all concluded that she left most likely out of nervousness and embarrassment and I'll admit, I've done that a couple of times when I first got FFXIV.
But it's justified as I would usually get really rude and mean people on my first runs who would tell me that I had no idea how to heal, and while it was true, I'd rather someone take the time to explain my first job to me then to badger me about and not make me want to scrap the game. That's why I make sure other people have good experiences; gotta fill this community with good and not full of elitism and intolerance for new people.
