you were suggesting to add a hotkey function to toggle between melee/range mode
It was my topic that Ragnarok's referenced, and no, I did not suggest such a thing. Why would I do that - it already exists in the game. Is my English THAT hard to understand?
while I was suggesting making the skill icon automaticly changed(flipped) to the one corresponding to the currently equipped weapon's type.
I can't say I like the idea of flipping icons. They double the amount of glyphs we have to memorise, compared to what we would have if there would be only one weapon-agnostic icon per manoeuvre. This way, there would be at least a slight chance that Menacing Attack icon will actually create an association with a menace, instead of being a bunch of random lines.
We already have a strong visual cue of the attack type the character is going to make: move the mouse over the target, and you will see.
