We've all been invited to raids that were already in progress, it's a fact of life. Someone says in trade that they need a healer for 10m ulduar, and you send him or her a message, "Fresh?". The reply is almost always "Yup" or "No but only 2 bosses down". This is perfectly acceptable in my opinion. What is not acceptable is what happened to me a few days ago. I got invited to a 10m ulduar, having been told only a few bosses were down. A few to me means like 2 or 3. 8. 8 bosses had been killed, and i didnt find out until i saved myself. That is unacceptable, and down right mean. If someone asks you how many bosses you've killed, be specific, please.
