I can't be mad at him, I got 2 groups recently. I had my shammies trying to farm the necklace from SM:Cath (7int, 7stam, 7 spi). I walked out of UC and a 40's druid buffed me, all of me. I know he had to use CTRL-Tab, cause my alts are all on top of each other and he did it quickly (I was in wolf form). So I thought, really talented, nice druid, and I thanked him twice. He said no problem, not just NP, which is what I do. Damn, it must be a sign. I told him I was going to farm SM and asked if he wanted come. He did and we rocked hard. Yeah, 6 people, all lvl 40's in cath is too much, but still it went quick. I never got the necklace in 4 runs, but they only took like 1 hour or so total. He mentioned he wanted to PVP with me. That would rock, dedicated healer and DPS person. We could watch each others back with my healing and his stealth, the possibilities are endless. Final result, great times had by all.

I went to Maraudon to just get exp (4 alts were 46.1 and one was 46.9). I grouped up with 3 others and we rocked the house, orange and purple. I don't remember the exact time to do it, but it was fast, no downtime, constant DPS and movement. I will miss the ability to see upper content with more people than needed. I wish they would let us 10 man stuff that only needs 5 man so lower geared people can at least see the content. I don't care about quests, I don't care about drops. I just want have fun and play with people. Anyway, it was a great time and picked up the Gizlock shield and the Landslide mace.

So, I can imagine a person just mooching off you, but try to have a positive outlook on it. It might turn out you have a great time. Good luck.
