I'm going to have to disagree with you, Dingu. PvE is one of the few action triggers when we are stalled in grams/lug. I don't think respecting 2-2 OPs is a necessity at all if there is no action. For instance, if there is grams camping with say 2-2 OPs, or 3 for creeps, or even one, freeps taking the rest could force the creeps to map out (because they/we can do that) to take OPs or other bonuses.
Doing this often divides the oposing side groups and has a chance of creating better action than our beloved pew-pew.
One of the biggest problems I see in Gilrain (and I know no other server, so I don't know if this is a general issue) is that creeps lack initiative to form small groups to move around the map and create action. We have a tribe where 80%+ of the creeps are and way too often you can see more than 15 people online there just sitting at grams or forming warg-packs that the only think they do is gank the ocasional freep that has been left alone.
I'm sure I'm being a bit unfair and I don't have all the information as I rarely group with most of the creeps (and honestly, the last time I tried to form a group using OOC I got no response cause there was already a group formed sitting at grams, so I don't see myself trying to form an open group anytime soon), but putting all the blame on freeps is unfair.
Also, freeps tend to justify their big minstrel balls surrounded by hunter traps by saying there are too many wargs. I'll tell you that most of the time there are so many wargs precisely because freeps form these kind of groups (even if not everyone is grouped with everyone). It is surely one of the reasons why I decided to start a warg, tired of being unable to find acceptable fights with my reaver around the map.
