Now that someone talked to me about Skateboard & Boombox, I MUST talk about them again ! ! !
I wanna reiterate again that Boombox CHOSE Skateboard over everything. And I mean EVERYTHING. Because genuinely, in-lore, supports must have it BAD.
For healers, they're either coveted or just overworked in general—and not to mention that they would definitely be the first targets in a battle. And supports in general aren't as useful as healers, therefore overlooked and possibly even mistreated. This isn't canon-aligned but this is mostly based from the lore we have so far from mainly the healers, aka. Vinestaff and Medkit. And even they're underappreciated by their own faction. (Vine, more so.)
So can you imagine what they would do to supports that DON'T heal.
And while I can't guarantee that Windforce would treat supports any better, or what Playground's views on supports are—(Crossroads Update please I need you so bad...)—you have to consider that you would be getting PROTECTION from a deity. Prestige, even. (seeing as Zuka got lauded for being a notorious soldier at the time, what more if you were being practically sponsored by a god?)
But despite all the cons and the least amount of pros in it for him, Boombox still chose to do it. Still chose to protect his friend. HIM, as a support, PROTECTING Skate, who is a melee. (When usually, it's the other way around.)
Boombox CHOSE Skate over a God and all the benefits that come with it.
