The delay is better than Mercedes combos i think; I land it the majority of the time.[/quote]
I have an easier time with my Mercedes. To be honest though, I button mash for combos, so I get a screen full of the little red messages telling me that I can't use the skill because I'm spamming it too much.
I still button mash for the Phantom combo, but I land it much less than Mercedes...I'm not sure. You can't hit Rapier TOO fast or it won't activate after Carte Mille...you also can't be a millisecond too slow or it won't activate then either. It's really just down to button mashing. I usually tap Rapier twice. It's become a habit...and sometimes I still miss. Guess you just have to train to get faster at it.
Mercedes combo is A LOT is easier, since you can chain the skills after their animations. But the Phantom combo you have to press the skills in quick successive, before even the first ones animation has started, let alone finished...
