No official one sorry. Stats of units change more frequently than Doctrine buffs, therefore we would need to constantly update that site, which is too much of a hassle. Also we are not using the forum anymore for info like this, in fact we will remove these articles in the future as everything is moved to our Wiki.
We actually have a site on the wiki about units which summarizes their characteristics in a more general sense so that this site survives slight balancing changes
