Would definitely recommend doing GvGs. It's a more controlled environment. There's less to worry about and you can just tunnel vision on the circle with your rotations. There's not a map queue trying to snipe you, only 15 dudes if that, nor a second squad trying to ajam, or a squad stealth bombing out of a blind corner. You can just focus on your rotations and reactions. There's also more downtime in gvgs too. The intros to gvg vids tend to be longer than the whole gvg and you get some dank music to go along with it. more likely the issue, is you need to ask the party that's complaining about your performance. What is their position relative to you? Most of the time when someone in a party complains about no stab, is because they're squirrelling in la la land and blows all their cds prior to a push. So video footage is better for review than taking said party member's advice.
