If we’re talking queue syncers I 100% agree, if we’re talking 2-5 people queuing together I strongly disagree.
It sucks to go against a premade but the reality is both factions tend to have 2-5 man premades. Some premades are stronger than others and/or sometimes it’s 2 man vs 5 man. There isn’t much to be done to prevent that, MMOs are also designed around community and multiplayer groups. Solo shuffle and blitz were introduced for solo players, random BGs and Epics can allow for multi player (with the exception of queue syncers because that’s an unintended manipulation of the system, if they wanted 6+ players to queue together they’d have allowed it without manipulation)
All that being said, I’m not a fan of graveyard camping behaviours. I try to encourage any people that I play with to focus on objectives vs annoying other players but sadly that’s what some people like to do. I agree that graveyard campers put a sour taste in a lot of solo / casual players mouths. I think GY camping is something blizzard could easily address though by allowing people to choose which graveyard they’d liked to respawn in and/or putting immunity bubbles like you see in IOC on GY spawn points, easy enough to do to stop deplorable behaviour (and to folks saying that people would abuse this by jumping in and out of the immunity bubble, easy fix is if you leave the bubble you can’t get the protection from it again until you die). It might still be a loss but it would prevent people from delaying a win if they can’t farm kills.)
