Exactly. People like that are the reason that I dont believe in the whole "only give advice when they ask you for it"-thing - because the people who need "advice" (or rather: an explantion of the most simple and basic things) the most are also the ones most oblivious to know about their desperate need to look up a tutorial or a job guide. They've cleared everything - or rather: got carried through everything - so they must be doing GREAT! They havent read their tooltips and took a minute to think about what they've read, so they'll be the last ones to (self)reflect after a wipe and ask themself "Could I have caused or prevented this?"
They need to get the message of "You're not doing fine, sorry" - personally I prefer to deliver that in the form of a polite message, either with exact advice or a general "Please look up a guide on your job".
The method of silent kicks might work aswell.
...even though, thinking about it now, we both might be wrong - they're not even reading their tooltips, so why would they read my advice... and they're not asking themselves if they made a mistake or could have done better after a wipe, so they probably wont selfreflect after a votekick either (funny enough that guy complained in his first thread that he wasnt kicked sooner - he was kicked at the last boss and complained about his time being wasted. So... if he'd gotten kicked sooner, he would have just jumped right into the next party, learning nothing)... at least after a kick they're not your problem anymore.
