I recently started my own Extreme FC LS on Zodiark and we've gotten a good progression in. At least we've gotten to Titan Ex Super Bombs.
However there was another person on my server who seemed to be rather aggressive in tells. He was upset that I told his FC member that he should place his Garuda egi off the side of Titan so it doesn't take damage when the floor falls. (Because he had Garuda on heel the whole time and it kept dying.) I also told him he needed to learn his rotation more because he wasn't using shadowflare ever. This FC member was their leader.
He told me I need to slow down and that I'm an elitist. I argued that I'm not the type of person to stay quiet and I think its better to try to help others right away. (I was not calling this person names. I just simply said, I think it would be better if you tried X approach.) Again I was slammed with the term elitist. That I should just let X person be and they will figure it out on their own.
So what I'm trying to grasp at this forum is that should I shut my mouth and let people play how they want to? I have never kicked anyone out of my LS or GRP. I have offered ways to help them improve their dps such as the class forums here and even I have watched videos on their class rotations for them.
The SMN thanked me for helping him with Garuda egi later on, but his FC leader since then has been very hostile - pushing that I need to get over myself. "It's just a game"
