I made the grim realisation tonight, that basically unless you run a 12 man-you can't expect teamwork with any realistic consistency.
We tried practicing differing types of combat tonight as around and 8 man. Out of about 6-9 drops, only TWICE did the other group(s) decide to work with us.
One group totally blanked us and refused to talk at all-after investigation turned out a non english speaking unit...another group decided that our brawler group didn't need any support-they were going to building hug and "snipe" from safety-NO MATTER WHAT, again their chat contribution was exactly ZERO, yet another group just blanked us and wandered off alone...
Every game we tried to talk to the other team(s) trying to get some co-operation going. Mostly it failed as the other group(s) simply refuse to listen or talk.
It's like playing in the solo queue at times....why go in group queue if you won't work with other groups?
What gets me is so many seem to have an issue with groups being "elitist" yet is there any wonder when people behave like that?
