isle queldanas Group Limit on blackrock

It would be more fun if there was the ability to invite more players in a team in the wpvp zone. Today we were trying to pvp as 4v6. We killed 1 but could not win since we are not grouped. I am maining healer. We cannot share buffs and heal each other. Our 4th died in 10 seconds since we cannot heal him in our group. he was all alone. not asking for raid group but more than 3. alot of battle seem hopeless because players always try to gank a group of 3. alot of mad people are there sadly always. but if 1 or 2 players could be invited it would make a much more balance zone. please consider, thank you for reading.
