Her new facet (bodyguard) looks good on paper but it is pretty useless compared to the original one she has, it is very hard to use (6s duration and 20 cd+ it is not perma buff on an ally) It might be good to buff an ally just for 10 armor but to get close to the enemy that always attacks target who you use E to is just frustrating playstyle and damage you make is base on Marci, no additional damage. the good use I could think of is when you combo with axe, LC, or Huska it can force the enemy to hit them but be able to get closer to the enemy who is attacking is using W which stuns them and they won't be able to act( attacking) and that's why it is kinda useless. Let's see the future patch, hopefully, they rework or make it better and easier to use.
