Why are low standards for dps acceptable?

[Vehementi]

Why should we form groups.DF should be serious.Give me a reason why its acceptable to perform poorly with unknown people?Saying because they are unknown is rude & makes you a jerk.And noone asks for the perfection,we ask to give it you max by using your toolkit,& to be open for advice.

Because you will always be at the mercy of RNG pairings no matter what. For better or worse that's what you get from pugging. You don't like those in pug groups don't pug.
Random grouping serious?
Well if trash is already dieing fast enough or too fast to keep stuff off cooldown for the upcoming boss fight. Why blow your heaviest hitters?
'Don't want perfection but want 100% your best...' You are reading what you are typing right? At this point I can't tell if you're sarcastic or not.
The person in question did change their rotation. So they were open to advice. OP admits this. Yet still acting like an ass and risked getting their party killed just to fluff their epeen.

That's what the kick function is for

You're misunderstanding this a bit. We're not talking about saving skills like Raging Strikes, or Dragonfire Dive for a boss fight. There's a difference between holding off on using those on a trash pack that's about to die and not using your skills that you get while leveling.

'Don't want perfection but want 100% your best...' You are reading what you are typing right? At this point I can't tell if you're sarcastic or not.

There is a world of a difference between min-maxing and using all your skills. The least that is required of your job is that you use your skills. It says here that you're a level 40 arcanist. You, for example, would not ignore your DoTs and just Ruin spam.

I agree that it's good that they changed their rotation, but if you get defensive when someone asks you why you're not using a skill like Enochian, that redefines your entire rotation, you need to get your attitude checked.

I was not talking about the BLM here, but in general. Everyone should be using his available tools and be open to advice, I'm also still learning stuff.
And no being perfect and give it your 100% are not the same.

As for why I pug? I pug since I have different play time than most of my friends, and we don't always need to do everything together.

Also, I loved to be paired up with RNG players, it's a good way to learn and interact with people, even if it's short.

Again DF should be taken seriously, you do it to get a random group to do the duty, not to mess around and be a burden.
