Burst heal? Unsustainable burst heal < sustainable heal.
Sure, even though Phoenix is mostly a burst heal character it doesn’t change the fact that he’s much better in combat/defending than Sparks, and can heal a group of people much more effectively.
Sparks has burst single-target heal, that leaves herself vulnerable and has greater total casting time to get both her and her target to an appropriate amount of HP.
Phoenix can contribute to a fight, then heal friendlies and himself to get them back into the fight again. Not only that, but he could self revive, allowing him to hold an area more easily than other medics could if he’s out of LoS when downed.
Sparks can’t do that. She has ranged revives and her healing ability is on a 10 second cooldown per pack. In order to get a 100 HP burst heal she needs 20 seconds after to do that again. Phoenix trades in casting time for a much stronger HP/minute heal, and increased ability to take damage and kill things.
This is coming from the fact that a 10 second cooldown time for Phoenix is just an indication the player went overkill on the medicine. For Sparks it’s normal to have a 10 second cooldown for a 50 HP heal. A very high estimate for Phoenix’s casting time in that scenario would be 6 seconds, but leaves Phoenix vulnerable for very little time.
Sparks, in order to do that, needs around 1.5 seconds, but is vulnerable for the entire time and has less HP.
Okay, with base stats, Phoenix could heal allies for 100 HP with a cooldown of 12 seconds. Sparks heals allies for 100 HP with a cooldown of 20 seconds. Phoenix’s burst heal is slower than Sparks, but it gives more healing per minute, at around 375 HP per minute or 6.25 per second. Sparks has, without the casting time, 300 HP per minute, and even then that could only apply to one person at a time.
Sparks has 20% less health than Phoenix, and her weapons deal 90% of the DPS that Phoenix’s weapons could do, assuming that Sparks has the highest DPS weapon she could carry while Phoenix has the lowest DPS primary he could carry.
Sparks does have burst damage in CQ, but it’s basically a shotgun that you have to aim. At least Aura has the best ability in the game. Sparks has the worst healing ability, the worst weapons, and only a marginally better revive than most medics.
Comparing Sparks’s healing to Phoenix’s is like comparing the FEL-IX to the MOA. The MOA is better even though it does less burst damage. The same could be said about the Healing Pulse.
