THey may not flag you, but when other people of the opposing faction intentionally flag cause it's shared questing areas, with alot of active combat ongoing, to get you flagged because the tab-targetting/auto-targetting functions in the game aren't the most robust, and flag you because of that, it isn't your choice.
Stop tab targeting and mindlessly attacking? Or is that solution too obvious.
If this is the problem how is it any different than every other area that is crowded by both factions? If it is the guards attacking that is one thing that probably should be fixed but if it is players tab targeting on accident that isn't something that needs fixing, at least on blizzards end.
Just a bit disengenuous.
Let's take the quests that are inside the cave for example. The mobs are fairly dense in population which makes pulling only one damn near impossible (the mogu mobs are linked to each other so there's two right there). Now then, I'm pertinere forced to not use one of my own talents (Harvest Life) because I don't get to choose how many targets it hits, it doesn't 'only' include targets I'm actively attacking it hits every single possible mob in its "range" including critters. Now then, let's add a flagged Hordey in and I have to change my whole style of play just to prevent from being flagged. Has nothing to with mindlessly tab targetting.
Now let's say we have a flagged toon stealthed. Now let's say I use my felgaurd to felstorm some mobs, all he has to do is walk near, bam, mission accomplished. The fact that you are almost prevented from using AOE really affects gameplay. Now what if a flagged toon pulls a bunch of mobs and starts running through the cave, but not far enough that the mobs leash, gets close to me and drops into stealth or aggro drops, then by proximity they start attacking me or my minion who may have already been engaged. Now I'm almost required to AOE to bring all these mobs down and doing so opens me up to being flagged. Not using any AOE A: puts me at risk of dying due to too many mobs... B: increases the time needed to complete the quests I'm trying to do in the first place in a timely manner.
Bottom line is in the highly populated areas for PVE mobs, like many places in Dread Wastes just as an example. it's quite easy for anyone who wants to grief players to 'accidentally' get people to flag. The new quest-area hub is highly populated with stationary as well as patrolling mobs which means you already have to be careful about pulling mobs intended or unintended and it's way easy for some classes at least to get another class flagged.
OP has a legit beef and I agree with him/her. PVP is a disgrace at present and World PVP is almost never balanced as it is, so the situation is only exacerbated.
