Observations From A Relatively New Player

[Saseal]

Careful of stereotypes. Plenty of vets will take the time and help out new players (I'm in an FC full of them).

Exactly same and agreed. Not all vets are like that.

I've played since beta and the day FFXIV opened (so I guess I can count myself as a vet), but I'll (and the rest of my FC mates) still give pointers and advice or mechanic explanations if someone says their new - or try to encourage newbies on tough fights (I usually encounter a lot of new players in a single DF party in Ultima HM), 'not to worry - it's a tough fight and not always a win. Nature of the beast - you'll end up running it a few times, so don't get discouraged. Wipes = learning'.

Just sometimes, it's difficult to do that (such as my example) when already amidst the chaos.
But I'll never flip out on people/new guys or refuse to offer help or explanation.
When I do dungeons, and someone says they're new, I'll stop to explain fights - even if this means standing outside and a bits away from the purple boss line to keep anyone from pulling if I feel the tank or party are moving a bit fast. I'm usually WHMing, so I usually use myself as a deterent from them running in without the healer.... thus waiting until I explain =p (doesn't always work, though...)
