To start, I love the skyscale and the fireball, nothing more fun than firebombing a group on your way to a fight and then participate on the ground.
But I'm slightly annoyed at the rise of super lazy players always finding a way to do next to nothing but gain rewards
And I don't mean low APM minion builds or chilled Mech builds, those still absolutely add to a fight. (opinions vary of course).
I've seen it in Dragonstorm, Soo-Won fight, Heitor's Gate (right outside the door shooting in).
People flying just out of sight or above casually doing the absolute bare minimum THE ENTIRE fight, in order to reap the rewards other players are actively trying to do. Not only scaling bosses making them harder for casual players but also not adding anything of use or value to a fight like dps or boons..
It's a mild annoyance. A fun gameplay mechanic slowly turning into who can do the absolute least to still make max gains.
EDIT:
To clarify I'm not complaining about using the skyscale in general or in a fight or whatever.
I'm specifically calling out people chilling off the the side somewhere basically AFK using fireball the entire fight to damage enough in order to gain reward.
