350 hours moira here.
I have simple rules, and while I don’t think I’ll ever heal like what is expected, because thats my playstyle and f you all =) I will give you what my intuition tells me is right, and I’ll even give a quick reason why. I hope this clarifies why Moira does what She does.
Situational- First and foremost, Moira is a chameleon. If there is a DVA/road combo and I’m single healing, I know its going to be VERY healing intensive. If its 5 damage, I tell them to come to me for heals. Here’s the tricky one we get yelled at alot for. I call for their mercy to die, there is no flanking, doesnt look like we are going to get point, so I go jungle and infiltrate their heals 2v1. I win about half the time, or more, or i wouldnt do it. Is it smart? Well it’s about winning the game by any means.
My strat for moira is pretty simple. The most bang for the buck clearly is a damage orb for getting mana back, (between orbs) primary attack works best but shield tanks are messing that up alot, and ranged, which overwatch is more geared towards at the moment. Why damage orb? Its not better if you get the full use out of each orb, I’d say its 75% then, but I might get a full use out of a healing orb 40%, and I’m VERY stingy with my healing orbs. If i threw out orbs like how others want, that number would be 20%. Damage Orbs I get about 80% effectiveness.
So now that we have that said, mana- Every Moira’s bane. I have found that above 75% i can heal through anything fast, say given a burst of 5-10 second damage. After that, I’m spent. Moira’s heal has a bit of a HoT on it, so I will really use it sparingly out of big combat. GOING IN TO A BIG COMBAT I WILL USE A DAMAGE ORB, THEN SWITCH TO HEALING AFTER THE COOLDOWN.
Why, you ask? Because someone who is dead deals no damage, and my mana is not infinite.
When I am below 50% mana, damage orbs are still the best way of getting back mana and generally I’m out of combat and trying to use primary. Sometimes, hell alot of times, my primary isnt getting me mana back, and people are all behind shields. So i can maybe throw out a healing orb that will get 25-50% used, or get a 100% on damage and maybe kill someone and save my mana. But I DO throw out healing orbs when OOM, that only accounts for…2% of my playtime, i almost never run out of mana. The best moira play is do heavy damage, kill everyone, heal up. I will wiat for people to get to 50% health because then they have a come to god moment and seek out heals, so they bunch up and i can whack them fast.
Train your tanks and damage. Also, stay behind shield tank unless neccessary to flank. Flanking I might do once a game to try, or do it several times because we aren’t moving the ball on offense. I rarely flank when playing D.
This all being said, I’m sure I left something out but don’t want to go too long. I like the one post where someone said they were giving the edge in the match somewhere. As a Moira, you control the game more than anyone else. Also, mercies are pincushions, Ana is the best healer IMO, zen is OP and underplayed, best synergy in the 2-2-2 roles with main heals, bridgette…and lucio are situational.
