To clarify glider and falcon can be used by anybody regardless of skill. However, in the case of glider (and possibly falcon) there is quite a skill ceiling not seen in other kits where players who practice and are good at the kit will absolutely see benefits. there is a vast difference between the usage of glider seen by players like ZachDontFall, Me, and few others that is not seen in players who dont spend the time to learn the kit and turn it from a running away kit, into an agro superpower
TLDR: BadBoyHalo is a big noob and needs to nerf glider
