Azalina is an mage support that has very large range heals on a delay. She is great for helping divers as she doesn't need to be close and in the fight. Be careful in using all of your wisps in one ability as you will either have a long cooldown for your heal, or a long cooldown for your damage. The healing does have a long range, but requires a distance to travel. You can adapt your buildpath to either become more a healer or a consistent damage dealer. Azalina's ultimates are great for teamfighting. Unfinished business lets her use less mana because she heals more and her abilities cost less. Witchwood's touch is a great ultimate in small compact areas where the trees may both heal and damage. Talents such as overwhelming rush can be useful when going against heroes that have low cooldown abilities giving them more time before the silence so the silence can be longer. Having only one cc ability in her kit makes her open when that ability is down so taking harsh screams could help her peel or cc more targets in a lower amount of time. For what she has in burst healing, damage, and an almost global presence, she lacks in cc, consistent healing, and being very reliant on her passive.
