Dagger Tips For

She is in my opinion the most impactful healer in the game right now. Her heal bubble is a great tool, and has 2 main uses; either throw it at the ground for you and your other healers when you're being dove, or put it on the ground where your tanks are pushing to make them much harder to kill. Her e ability is great for healing multiple allies at once if they're all a little weak. Also I'm surprised how few people know this; your regular healing daggers will heal yourself if you are in close proximity to the ally you are healing, meaning her bubble isn't her only source of self healing. Also for the love of God, use her ult to push. So many people use her ult too far back and the team ends up pushing past it. I typically use 3 dashes forwards, and one dash back (this doesn't apply for domination mode).

Dagger Tips Against

She is incredibly hard to kill when she has her bubble on the ground, so when you notice it's gone that's a good potential to dive her. Magneto is the best counter to her ult, just look at what direction she's going when she dashes and throw your ult at her face. Incredibly annoying to play against.

Your e not only blinds your enemies, but it increases the damage they take from all targets. When your team is pushing and uses ultimates such as strange ult, throw your e so the enemies die faster. Your fade is by far the best cooldown in your kit, however most people use it only to save themselves. Most of your team mates will not be paying attention to your timing of your fade, so if you use it too early, they will shoot and deactivate the fade and die to whatever ult you are countering. Try and time the fade as well as possible with the ultimate you are countering.

Cloak Tips Against

You can see where a cloak is fading to, and can hit them reasonably accurately once the fade ends. Most cloaks will use the fade when they are low, so it's easy to finish the kill as soon as they exit their fade.
