[2020] Johanna vs Diablo

Johanna is a generally powerful tank and is more meta right now, so you’re good picking her pretty much any time. She does shine more on maps where waveclear is more powerful. She’s particularly valuable on maps with two close lanes that consistently need to be cleared, like Tomb of the Spider Queen and Dragon Shire.

Diablo has traditionally been more powerful on certain maps. He can absolutely dominate games on maps where teams fight in small corridors such as Cursed Hollow, Infernal Shrines, and Towers of Doom.

Everything being equal, Johanna is the safer pick more often, but Diablo can completely win the game for you, particularly if you are more skilled than your opponents and are reliably taking advantage of their mistakes in positioning.

There are a lot of good ones. When you’re picking Diablo as a tank your initial best strategy is to kill one enemy very quickly when they’re out of position. Therefore, heroes who bring follow-up CC to his initial burst of offensive power are generally the best.

Healers that i’m happy to see when i’m Diablo are:

1. Tyrande - There’s a reason this is a tried and true combo. Tyrande provides both follow-up CC and vulnerability on the target he charges. The combo does take coordination to pull off though, so unless you’re on the same page this won’t work well.
2. Uther
3. Malfurion
4. Deckard (his CC is a little slow though so it’s best to have someone else who can more reliably follow up Diablo’s Stun)
5. Anduin

Really anyone who has reliable CC is optimal. You can get away with soft CC like Stukov, or other useful debuffs like Ana’s Grenade as well, but it’s not as easy to pull off as simply CC-chaining Diablo’s target and killing them (these heroes are perfectly fine if someone else on your team is providing the follow-up CC instead of you).
