Meaningless buttons are:
-Exist only to create more buttons to press( but doesnt have further use or impact beyond that)
-Botton that are very similar to one another... Why have 3 abilites that is roughly the same.. but with diff dmg/cd?
-Situational based buttons: the type of skills you will forget you have, bc of how rare you use them..
Differnt abilites is not itself bothersome..
but it does become an issue when they become to many..
and often time many skills = many of the same skill.
