In the same token, they are not paying for my subscription either. However, they are hampering my enjoyment of the game by playing the way they are playing because we might be wiping over and over again to the same boss and the person in question may be the direct cause of this wiping. Is it fair to myself that someone else, who isn't paying for my subscription, be hampering my enjoyment of the game? The coin can be flipped both ways in this regard. We're playing an MMO here, there should be a general level of respect and good play for the enjoyment of everyone we play with.
You are making the assumption here that I present myself in a negative light when I offer my help to other individuals.
-In my AV example previous, I was in that AV with a PLD and BLM both from my FC. We said nothing to the BLM, we made a comment about the BLMs playstyle in FC chat, but ignore the individual because we knew we could carry the BLM to victory. No words of ire arose from anyone.
-In a Pharos Sirious I had for DR, I was with a BLM who wasn't quite sure how to do his BLM rotation. He always was going from Fire to Ice half way through and never really throwing out any significant damage. I noticed he was also wearing AF mostly and seemed new to the 50 scene in general. I politely asked him "I noticed you're a new 50 BLM, would you like any help with your rotation?" He answered with a courteous yes and I gave him a few pointers. His rotation was still a mish-mash of buttons at times, but he was learning, and that's the important bit of the lesson.
-Generally, when someone mentions they are new for a a dungeon at the beginning, I make a point to state I can give them a few pointers when we get to the bosses (or any particular mob of note). We get to the boss, I usually run off 3-4 points to look out for without being prompted, and then we engage. No irksome words are exchanged.
HOWEVER, I will agree that many individuals do present themselves in a less than ideal light and this causes further strife and ire to be brought forward from both parties. In this particular case, yes, I agree, both parties are at fault. But your assumption that all "advice giving" leads to altercation is false. Just it "mostly does" given the negativity / elitism that many individuals have.
Mmm, the power of Unfrozen Water Armour on a VIT built Scholar was so fun. Jupital Thunder, eat your heart out. And then swapping to an Evil Druid Silk Robe to deal with other pesky Scholars =DDD Ah, the memories ~Wistfully remembers~
