I just had someone invite me to a raid. there was 4 of us level 40+ I am level 44. And they all jumped out before the raid even started and didn't invite me again. What noobs we could of easily done it in my opinion. This happens all the time. I was able to DUO Thundurus and the people I invite always jump out if theres only 3 or 4 of us lol. Its their own fault for being so noobish not even trying.
