I feel ya, I only recently returned to mass effect 3 and unfortunately I came to find all of my achievements had been wiped. Further more, I lack in equipment and weapon upgrades due to having quit shortly after my first play through. Still, I can perform with the best of them on platinum difficulty, but my most recent game was with an individual named 'powerdandy' and well, let's just say I spent twenty minutes getting yelled at by a grown man whom has the patience of a ten year old and, I suspect, the intelligence of one as well. Though he silenced himself once I started to catch up in score. In any event, I succeed in nearly every single platinum session that I participate in, but it seems like there are a lot of try hards out there. Equipment isn't even necessary IMO. all the difficulty is is a boss spam simulator.
Just ran into this powerdandy for a couple games, el kittens was there too and some other random, we had a couple awesome games and then I had to split. Good team player but no voice chatter on the mic, wonder if it's a good day/bad day thing or if they just get along better now. Tried searching their name on the forum, got this post as a hit.
