GB combat issues

[quickness]

I know I've seen this mentioned in the past, but it seems like it is still a problem unless I missed something, but the combat response from mobs that come up behind you as you are gathering with GB does not work well at all. Majority of the time the toon will just sit there and let himself be attacked from behind until dead. Sometimes he will start swimming away from the attacking mob and then die or he may occasionally turn around and fight back, but that is the rarer of the cases. Is there anything in the works to make the combat more responsive at least to the point where it does a better job of not dying so easily?
