The current trend of Dakota adding two-skill mercs with only one action has necessitated an overhaul of the wiki Squadmate template. Now each merc should display if it is Single Action or Double action in the infobox. Before, we just knew that all double skill mercs were also double action mercs, but this is no longer the case (for example: Lethals like Boomboxer and Biofuel Bengal are single action).
In order to support this change, I have updated my FF JSON Parsing Tool (http://www.m-webs.com/ff/) to include Actions in the wiki template, along with a number of other improvements that should make it smoother to use. All new characters created with this template will correctly have their actions parameter set.
However, the Action field is not defined in any of the old mercs that do not use this new template. You can tell by the fact their Action field is listed as 'Unknown.' This means all old characters need to have their wiki entries update to be either SINGLE or DOUBLE. Have fun!
Edit: looks like a lot of skills need updating too thanks to this new 'rebalancing.'
