Yeah, that will do it. Looks good. Then I'm ready for the true drakanthropes.
I believe we were still sorting out how to deal with ability adjustments, sizes, etc. If I've picked the right posts (#1294 to 1299 or thereabouts), the latest proposal is to use wyrmling stats to create the weredragon but allow advancement either by character level or additional true dragon HD, which can also lead to hybrid/dragon form size increases, etc.
I like that, let's do it.
I vaguely recall there being some extraplanar or spelljammer true dragons which bigger and/or stronger, starting out as Large sized wyrmlings or Medium wyrmlings with Strength of 19 or more but might be misremembering or thinking of non-WotC 3E dragons.
No, no, wait a moment. We just agreed to use the wyrmling as the base dragon (and that's what we were thinking before). So no need for any complicated tables. If the wyrmling and base creature are more than one step apart on the Changes to Statistics by Size table (which looks like the standard SRD one, right?), just use all the adjustments for all the size steps to get the dragon form Str (or else use the base dragon wyrmling's Str, whichever is larger).Updating the Weredragon (True Drakanthrope) Working Draft.
We need to modify the Changes to Statistics by Size Table since the true drakanthrope template allows for a very wide range of sizes in Dragon Form.
i.e. Tiny Base Dragon (brass wrymling) and Colossal base creature (mountain giant) for a brass mountain giant weredragon.
I would also allow for the possibility of particularly powerful weredragons whose base dragon stats and abilities are better than Wyrmling, such as a Young Adult Fire Giant weredragon or whatever.
We could do a matrix of sizes (i.e. hybrid form's size in column, dragon form's size in rows or vice versa) or just use size changes; i.e. STR –2 or –4 if one size smaller, –4 or –8 if two sizes and then add another –8 for each additional size change.

To get a larger dragon form, we agreed to allow advancement by dragon HD. With enough dragon HD, the dragon form goes up in age category and often size, so the Str (and other ability) adjustments change but still follow the same table if necessary. Does that work?
Though I wouldn't mind having a way to boost mental stats with dragon HD faster than usual ability boosts.
