I also agree. Maybe not to all of listed skills, as some that are listed already have use like thunder storm, but most classes have only one set of "good" skills to have and there is no reason to choose others or build different strategy. But I think to change damage alone is too generic and maybe status effects can be added or changed a little to be more useful? Or if possible to change the effect of some skills to be more skill and less auto attack.
For example LKs counterattack, maybe make it shorter with longer cool down, but can counter melee skills as well?
