that i have come across over the recent year or so of experience
1) newbies: they dont have a lot of experience in group games so they put most of their effort just trying to get their footing/stay alive. underestimated but often times suprise people.
2) big namers: these are more players who were big names in the previous gen of big name group games. they dont have much go prove so they play with a decent amount of effort but they know where/when to channel the effort and when the time is right. usually play to the situation
3) active but not big names: the less known (but at times just as experienced/accomplished) group gamers that are usually newer-ish to the site. this is where 80% of the tryhards fall who obsessed with BIG MEWVZ and will include you in a group mail that you say one message in and then you wake up and theres a "50" next to your mail icon.
