This is not the ability to mark targets. Anyone can do that. This is a marker that you place on the ground which has one of the role symbols like from group finder. They are available now as consumable items in cartel packs, and this is making them free and unlimited for a small one-time price (credits or CCs). This convenience item is legacy wide, not character perks, too! Which is what I’d have figured they’d do, for a credit dump.
I would have liked to have more then three markers though since positioning can be more complicated than three positions. It almost defeats the purpose to have this feature and only have three symbols. What if there were only three targeting symbols? We ought to have four or five. Hopefully this will come later.
