On those type of games, you can just encourage your team to do the right play. And you can keep trying, do what you think works best for the situation. Get in front of EFC so he may see you as a troubling presence, and he will stay there (Lol, it works trust me, i was playing 20 resto druid with attack power set, and there was a 29 resto druid who used sw pots and dash, i went in front of him, and i can honestly tell i WOULDN'T have done ANYTHING but just stand there, and he didn't get past me, he thought i was gonna 1shot him, this ofc will not work if efc is smart. But its worth a shot.). if you are a frontline, even if your team wants to farm gy, you can drive them wherever you want, they tend to follow a player. That works best on a boomy / bm. So, if you are able and think you can sustain efc by just your presence there, and wait for team to catch up and actually have a kill on him/her.
