Guild Wars 2

Even without a group it could be useful to have a target.
E.g. “Subject 7” (??? not sure -> the slime in Queen’s Gauntlet)

I had the “oh you hold the right mouse button to strafe? I’ll mark the selected enemy even if you did not use the left mouse button”-bug, lost the “boss” and was unable to find it again… and failed the fight with 5 open gambits…

without a group it should be possible to realize just by a few changes in the client (the server should not need to know about that since the information will not be passed to other players?)
and it could help a lot – especially when all enemies look the same…

Would definately be helpful to let us do this.

As a small work around you can invite an offline friend / guildmate to a group and have the target marking ability, but I agree its something that needs an option for solo playing with the nature of the combat in this game.
