PSA: Karma was at her healthiest when Mantra E dealt damage
Simply because it could actually fail. It had an optimal use case (full 5 man shield and damage), and two less efficient situational uses (purely offensive or purely defensive). Now that Karma's RE no longer has a damage component, we are presented with the following issues:
- All of RE's power is concentrated into the shield values, meaning in order for this spell to be good or even viable the numbers need to be inflated. The spell then becomes problematic because it's strong whilst also completely lacking counterplay, hence the current nerfs.
Remember what RE was like before her shield was buffed (patch 6.6) and the support items were updated with % heal/shield (patch 6.13)? Yeah, it sucked. Removing REs damage was a massive back step in design, especially when you consider successful Enchanter abilities like
's W. Similar to Karma's shield bomb, Nami's W has an optimal use (heal/damage bounces) and two less efficient uses (just heal or damage), something both allies and enemies can play around.

Her passive had to be buffed to compensate for the loss of REs interaction. This made her kit a lot more forgiving, essentially giving access to more Mantras for doing a lot less (bad idea). The passive buff also spawned a nasty little tumor in top lane known as "Tank Karma", which saw her W go from a DoT ability to a point and click LeBlanc snare to nerf her RW passive interaction (perma healing).
-
Drastically lowered her skill cap. As a champion essentially based on decision making, making her decisions obvious (or brain dead as some would say) immediately ruins her. Then we end up with a low skill cap champion who can be poor in solo Q and yet dominate in competitive, sort of like a weird reverse Ryze/Azir.
-
Completely killed her theme. I know for the most part Karma lost her duality theme in her rework, but they kept her shield bomb (because it was iconic). Now thats gone, what theme is there? Meddler says shes lacking in "thematic delivery", but really, what theme is there to deliver on?
Genuinely wish a Rioter would give a definitive answer to this, but it's been asked many times and never been answered. From that one can assume that there is simply no answer. There's been speculation on whether or not her title "The Enlightened One" is meant to be her theme, but if that's so they also killed this theme when they took REs damage and simplified her Mantras.
The point is, the decision to skew Karma's balance more towards being an Enchanter ruined her because she inherited fundamental Enchanter issues. Lack of/or poor counterplay, low interaction, overlapping strengths, overly simplistic, anti-fun to be against etc... These ladies here >
