I’m really enjoying post-nerf Ambra on all counts except one.
Starting up the lifesteal beam requires you to be much too close to your enemy. After the nerf, it’s on shorter range, with less damage and overall less life steal, but I’m ok with that side of things. I seem to be able to maintain the beam for 3-4 times further distance than the initiation, and it just feels horribly clunky and makes her feel less fun.
Knockback in PvE is plentiful and drastic, so having to run into an enemy’s knockback range just so you can initiate the beam normally results in you being flung outside the maximum beam range. I’m fine with it staying the damage and max range that it is at the moment, but its initial casting range needs to be the the same as or closer to the maximum range.
If for some reason it makes her OP, adjust her in other ways. To me, the playstyle of a character is the most important thing, and having an awkward mechanic like this just detracts from the fun of her kit.
Increasing the initial casting range of her beam means you still need to be close to your enemies, but you don’t have to bury your face in their armpits just to tick a few points of heal up before you get attacked. The beam should be there to leech enemies while you try and strafe/kite them, or leech enemies that your allies are engaging, to keep yourself topped up.
Just my opinions, but comment if you have an alternate/better solution, or if you’ve got justification on why it shouldn’t change
