Firstly, this is not a buff/nerf post. Besides Vikings would be in a nice spot right now in terms of balance, this is just a personal list of changes addressed to give Vikings a new gameplay more appealing with I think Vikings “should” be played (aka Agressive infantry civ)
-Swap UT’s: Chieftains to Imp Age and Berserkergang to Castle Age
-Berserkergang No longer rise the regenerate healing ability of Berserks, instead gives berserks the ability of build rams and Siege towers (yes, just like generic infantry in Age 4). After see several games of Age 4 i like the dinamic that this feature gives to the game and I think it really fits with Vikings. Of course, siege upgrades still require a Siege Workshop
-Berserkergang cost changed to 300F 300G
-Berserk’s regen rate rised to 30 HP per minute.
-Berserk cost rised +15G. Obtain +1 PA
