Ashe needed lots of buffs and basically removal of barriers and nerfing support healing for people to suddenly figure out that boosted dynamite spam and suddenly consistently hitting scope shots at fast ROF is actually broken af. Damageboost ain’t doing anything if your ashe misses every scope shot because the scoped in sight was so wonky and inaccurate.
Early ashe had lots of hitreg problems. They fixed most of ashe’s issues, gave her loads of buffs and suddenly she broke.
