Ok, so let me drive home a few points in a friendly tone :-) (Corbon already did this, but I just can´t resist).
1. The rules are erroneously written and only work for 2x1 creatures. Taken as RAW, for 3x2 creatues sidesteps are definitely allowed, while forward movement is not. Which is obviously ridiculous.
2. The rules need interpretation/modification for the 3x2 creatures (again, for the 2x1 creatures they work perfectly).
Feanor et al. interpret/modify them in a way that forward is allowed, sideways is not. Basis: Allowing forward is obvious, but disallowing sideways ?
I for myself (and obviously Big Remy as well) interpret/modify them in a way that forward and sideways are both allowed for the dragon, forward only for the hellhound (and blood ape). Basis: Sideways is allowed by RAW, forward is allowed by extension and logical interpretation.
Both interpretations/mods are houserules - so please don´t tell anybody you are moving dragons according to the rulebook!
3. The blood ape example in the FAQ does nothing to clarify the situation - they are not allowed to Leap sideways and must move according to the rules - fine. In all our interpretations and according to RAW they were never allowed to move sideways in any case.
As Corbon said, it is still fun discussing this. Yet I doubt any further arguments will show up.
