What is with people?

[Vidu]

People are very sensitive these days. Honestly you're better off letting it slide off or at least have some fun with it. People in a run don't like me? I spam emotes, especially the ones I made using macros, and leave them to their fate It's been a while since I've had drama in a dungeon/raid though, except in Heaven on High a while back because I didn't feel like chasing silver chests and made a post about it. People just play different is all.

There is a difference between "people playing different" and "people playing in a way that prevents the rest of the party to clear the content in question".

I suppose you're trying to be nice to the OP here and I agree with letting that insult slide (or just reporting it silently) being not to bad of an advice, seeing how this got blown out of proportion a bit, but the subtext of "Just do what you want and dont care what people say" is really bad advice, specially in this case.
I dont know if you went through the whole thread, but you basically just told someone who was offtanking, yet in tankstance and spamming their aggro-combo, stealing the boss from the actual maintank, then proceded to place the boss in a manner that turned 90% of the arena into "the floor is actual lava that will kill you" instead of only about 50% and consequently caused a wipe - while also not responding to anything his party said to him... and you told that someone that its okay to just play differently.

People did not "didnt like him", because he was playing a Roegadyn or because of his glamour, but because of his actions which were directly harmful to the success of their run. His actions already appear as griefing and harrassing - add silly emote-spam to it, and I can only hope the GMs will see it the same way. That party would have been better off if he left them to their fate, because that fate could have easly been: Get a tank in who knows basic gameplay at level 70 and clear the raid.

If people in a run didnt like me, my first thought would be "Okay, what could be the reason for that?" and only after I have definitly established that the fault doesnt lie with me - if anything, by asking my party if they'd like me to change anything about the way I'm handling stuff right now - I'll conclude that they are a bunch of jerks who can look for a new tank/healer now.
Dont get on a high horse before you've figured out if you actually belong there - making fun of people who are legit upset about you because you're the one whos wiping them or making them all work an awful lot harder is the absolute worst thing to do in such a situation, because it shows that you lack one fundamental skill thats required for any group-content: team-work.

A paladin opener can vary between starting off with casting Holy Spirit - or with your actual offtank-melee-combo and you applying your DoT. You can also play differently in terms of actual skill in the sense of how well you manage to time your buffs and dots and how often you remember to use support-skills. Thats all "people play different".
But at somepoint its not "playing different" its "playing bad". Spamming aggro-combos when OT is playing bad, not "different".
As RDM you can play different in the sense of starting with your Thunder/Fire-casts or Stone/Wind - starting with your melee-combo and only hitting that while never touching your casts is not "playing different", its playing bad.

...there is a huge difference between having a slightly different, but legit approach at a class and just plainly ignoring 70% of your skills and not really understanding the other 30%.
Please - dont go around and tell people who need to improve that its okay to play different, because then they'll feel validated.
Tell them that its okay that they still need to learn - and if you can, help them with that!

But while we can kick for something called "Difference in Playstyle" that doesnt mean that the person who got kicked for that just picked an approach the party didnt like - the real reason they got kicked might very well have been "horrible playstyle", but obviously SE cant say that.

In short: Dont support bad playstyle or harrassing behaviour.
