So why do they even mention the remaining moves segment of the phase? I find it unusual that the rocks would be dropped but the damage would be worked out later. Parachute rocks maybe? It is unheard of for an attack to happen and damage be worked out later, most things in warhammer are resolved as they happen.
Screamers of tzeentch have a very similar attack, and they are described as only be able to use it in remaining moves phase.
I guess it is pretty rare that it would come up, you'd probably need to be on a hill with your terradons anyway, with a couple units in a line.
"I can't believe that for once a rule is written so clearly and because you dont agree with whats written and you think you know their intent was different to the rule conveyed, that you can point the finger at those with differing opinions to you citing them as trying to exploit the rules to their best advantage."
The intent is clear, but the rule as written has a SEMANTIC loophole in it. If the rule had been clearly written, there would be no reason for debate at all.
What you are looking for is free license to use your upgraded version of drop rocks and you don't want to feel cheesy when you do it, so you want people to agree with you. I for one will not grant you that absolution. We're probably just different kinds of players, I prefer to play the rules as the average joe would interpret them. I mean, most people who play competitively will have a passing familiarity with all the rulebooks. It takes a special kind of "research" to discover new abilities like this one. But I just see it as causing conflict when it comes to games. This is why I advise people against using things like the giant bow auto-skewering a whole rank and this thing. It's just something that has a convoluted explanation that would slow down a game or cause a conflict.
"I don't know about you but if there is a vague ruling that need carification, I have and will always continue to side with the common sense/spirit of game outcome."
Common sense would dictate that during a charge, you wouldn't be able to aim as well as not during a charge and you'd be more focused on hitting what you charge. This is why you can't charge and shoot weapons with any other unit in the game, and why I think that it better keeps with the spirit of the game to say drop rocks is no different.
I didn't think this even needed a FAQ, but now I guess it does.
