I have observed that most Rogue skills can only be used using a specific type of weapon like daggers and other melee weapons can be used. I can't seem to understand why in case of Slayer's Flurry, a Bow can be used but a One-handed Sword can't be used or a dagger can use which obviously a skill made for Blunt weapons such Anvil's Woe, and Bladestorm which is obviously for edged weapons can be used using a Mace or a Hammer, why not just name it Whirlwind or something. What I'm trying to say is to enhance the skills in such a way to make it streamline on what weapons can be used realistically with each skills. Also, for me, even if Infinity Blade is a spell, I think it should be possible to use it even without a Catalyst.
