What do you people think about different portrait-borders to show how elite is the mob you are looking at? Right now it shows "+" near the level of the mob, but I doubt this is how it's going to end up looking at the end. Archeage did it quite well, they had different borders with stars, but stars is something you need to count. How strong is that drake? Wait, let me count the stars... The best way it was ever done was in LOTRO, where the moment you targeted the enemy you knew immediately how strong it was, and you didn't have to count anything or memorize anything, it was very apparent. If it has a bunch of flames coming out of it's portrait, don't touch it!

Like this post if you think something like that should be added into the game.
