I don’t think current Lunara require any adjustments, aside the Abolish Magic. And for the reasons I mentioned above. Her kit is strong, has everything she needs and is capable of adjusting her playstyle to various situation. There is just this single, dead talent I’d like to make somehow more useful. It’s good talent, but not as option to strip Lun off of Let Them Wither or GSS.
The most severe problem I have when I’m using this talent is the fact, that as Lun I’m usually focused on dealing damage. Abolish makes me looking for potential saves in my team, distracting me from dealing damage or avoiding enemy skillshots. Abolish Magic should not be something you think and use on regular basis, but rather a last-resort mean to save yourself/somebody one gets a reminder about 2-3 seconds before somebody die.
I guess Blizz implemented this talent just as translation of her anti-magic abilities from W3, but while it works briliantly in W3, it has little usage in HotS. But apparently Blizz still want it to stay. I would make it baseline, with higher cooldown. Even something like 60-70 seconds. It should not be one of her core mechanics, but rather situational tool to help countering highly CC-oriented teams. Would work well in QM and bad drafts involving people picking 3 mages against CC-focused teams.
