The Sombrero card from Mexico, which increases the explorer's regeneration rate, and also gives Insurgentes a regeneration, is just TOOO much.
Insurgentes regenerates 1+ per second! And do not even need to stand by, they even regenerate when walking or attacking.
1.+ per second, almost 2 hitpoints per second, for a full insurgentes army is just tooo much, is not one single unit, but for all of that insurgente class.
I recommend to lower that regeneration from 1+ to 1> per second, and/or to make it happen if and only if the units are standing ground. Please fix, along with Krupp factories. Hope can be done for next patch or near future.
