This has turned into a no win situation, fivers have pretty much turned into unwelcome guests no one wants around but are expected to give access to expert maps. If we're a nuisance to the point lower egos want us gone, will they remove themselves from the game once they've reached the same level ?
As for the supposed "griefing" stemming from bumped threat levels, that's a door that swings both ways. Quite often stuff I'm doing at TL 6-7 solo (game seems to consider that to be what I should be playing at) gets bumped up to TL 10 by a couple of lower EGOs jumping in, only to run away after a few downs, leaving you to fend off hostiles at TL 10 (which is manageable) facing amounts of enemies tailored for 3, 4 or more players (which gets pretty overwhelming).
