Mediocrity should NOT be the standard for players in any content.

There's a difference between "Hey, I noticed you're using Aeolian Edge alone instead of comboing it, you'll do more damage if you combo into it" and "Wow, ninja, you don't even combo into that attack". One is clearly meant to be helpful, and the other is clearly antagonistic. I make this exact example because I had this exact thing happen in a Qitana run while leveling DRK. Ninja was just spamming Aeolian Edge, not comboing, not Hutoning or Suitoning. Bard was the first to speak up being directly antagonistic and demeaning towards the ninja, while me and WHM actually gave advice. By the end of the run, ninja was actually using trick attack (though huton was still a ways off) and was properly comboing. Bard was being a pi*sy jerkwad the entire time. Ninja eventually told us he only started playing the game a couple of weeks before and just didn't know quite how to play, only making it that far due to trusts.

Point is, tone matters. Context matters. You may think you're being helpful but you're not if you're going to be a demeaning a*shole about it. It muddies the waters of the discussion when you use the hyperbole of "being helpful gets you banned"; no, being an a*shole gets you banned.

Two things I would like to point out. Sometimes even by using your first example people will flip out and it's nigh impossible to convey tone via text. You can try and making a cutsey as possible but if the person on the other side reading it had a bad day i can garantee it will come off wrong regardless of your good intentions. It's all how you read things in your head and your current state of mind unfortunatly has a big influence on how you tone what you're reading. People can be genuinely trying to be nice but you can read it as sarcasm. Heck there was a thread in the healer forum where a good chunk of healers when being told that they were doing a good job thought people were being sarcastic towards them instead (probably because they get treated like crap most of the time to the point they fail to see when they're being complimented).

Things are not as simple as you make them out to be sometimes.
