Renders it somewhat pointless in PvP. The game moves fast enough that it’s hard to consistently click on something, and there’s no keybind to exclusively target players like in WoW.
It’s annoying to have a class such as a Mesmer targeted, only for them to go invis, and when they come back, have about twenty clones, with me having no idea which one is the real one to CTRL-T them again.
There’s really no reason why it should do this, anyway.
