I'm going to be very frank with you.

Witch and Wizard resurrects should be a ground target aoe that just works if the thing lands. Period.

The same thing is true of the med kits. 

Things just need to work. It should NOT be a MUD Game from the late 80s or 90s where your primary combatant is the menu system.

As well, you need a downed-state like Generation Zero when people are "dead" but not "dead". You could just copy the Guild Wars 2 revive system.

Why? Because this is buggy as crap. You instantly kill people with no tells or indications of what is happening and frankly, this has been an issue we have repeatedly told you about from the very beginning of the game. It has been the Standard for a reason, a very good reason, that a healer or other support function actually does the thing it is supposed to do. You've designed Black Desert to deliberately make it be as difficult as possible to use those particular abilities. Ground target AoE rez function because this menu system stuff is non-sense. Make a game or make a MUD. This might even be worse than a MUD when it comes to resurrection mechanics. Something approaching Eve Online where the presing resurrect causes a mini game through menu systems leading to an excel sheet and pre-med Calc Exam. Make a game please. Stop this nonsense with the support systems.
