I installed EB again - first time since pre 0.8, and I see there are plenty of improvements since last time I played

One consequence of the changes is however that I no longer know much about how (which government) to get good auxilia and where (which province/city). I remember there was some excel sheet or similar with this info, but I can't seem to find it, plus I don't have excel

If someone happens to know off the top of their heads, units that I'd be especially interested in info on, are: sotaroas, any heavy infantry (comparable to principes or better/larger unit size if possible!) available to recruit in Gaul or Germania, and finally scutarii or other Iberian infantry units. Slightly OT considering the thread title, I'm also wondering when the Camillan era ends and I get improved infantry?

Apart from this, I'm also interested to hear what strategy for auxilia units other EB players like to use in their Romani campaigns. Which units did you find most helpful? What auxilia strategy would you recommend me to use?
