In a project that I'm working on, for the most part each class has unique skills that are distinct from any other class's skills. However, for a few of the melee-heavy classes (knight, barbarian, rogue) I was thinking of giving them all a skill that is essentially the same in function, i.e. the ability to attack 2 random enemies on 1 turn. The only difference would be aesthetic, i.e. the rogue's might be called "double attack" whereas the barbarian's might be called "frenzy." All the other skills are going to be very different from each other, it just seems that the ability to attack multiple enemies at once is so fundamental and any class without access to magic is going to need this. So I guess my question is, should I still look for some other way to differentiate the skills or is the duplication of function acceptable in this case considering all the other skills will be differentiated? Would you feel annoyed if your DPS barb and your DPS Rogue had essentially the same kind of skill with a different name, or would it not matter as long as all the other skills made the classes feel different?
