I see people all the time complaining about toxicity/elitism/general jerkiness in the "raiding/fractal playerbase".
The thing is, PUGs are that way by nature. There's nothing that can or needs to be done about that. I've played WoW for years(late vanilla-pandaria) and raided most of that time. As many of you know, WoW endgame has a much stronger focus of raiding/group instanced content. Since the dawn of time PUGs have been cancer or something you do only once you got the content on total farm mode(hence the absurd requirements). For most of my days in WoW , PUG raiding was pure mockery, if you raided - you do it with a guild or your mates. In GW2 however, I see people that are completely surprised by the nature of PUGs and place blame all around except the right places. I believe the reason for this is simply that almost no content in GW2 nodges people towards communication. People expect to do raiding and fractals the same way they do open world group events and don't bother communicating with others( a crazy idea, communication in a MP game???).
I suggest to anyone who is still in the pug life scene to just stop. You will discover a whole new game.
Some easy and obvious beginner tips:
1. Join a Guild! Find a guild with shared interests and communicate with them. You will find that any boss/fractal doesn't need "meta" comps. Simply following the mechanics and concentrating on the actual fight will get you there.
2. Use your friend list! Say you encounter a decent player from anywhere who isnt in your guild, communicate and add them to your friend list. Next time you can contact him straight away and you got a competent party member!
3. Focus on mechanics over DPS, always. You can't do DPS if you are dead. I can't tell you how many times I've seen players who dont communicate and die from simple mechanics because they were in tunnel vision mode on their rotation and personal DPS. In fact, the difference between a really complex optimal rotation and an easier one is usually less than 20 percent. Always follow common sense and focus on fight mechanics. If you're raiding, focus on learning fight mechanics and don't tunnel vision the perfect rotation.
If you just abandon the PuG life you will find yourself having a blast in raiding/fractals.
