Why Lucian/Kallista will ALWAYS be picked more then Ashe
is an immobile ADC, she doesn't bring ANY more damage to the table. Her Arrow, reliable CC yes, but still the support can usually have CC or the Mage so its rarely needed on an ADC.
and
and
just have tons more mobility and ability to keep safe but don't do any less damage from Ashe. The problem with their design is there is no loss in damage or a trade off for the mobility that they have and hence why they are always going to be used more because they are more forgiving.
