Eh, when I build and paint models the bases are one of the first things glued on and one of the last things done. Definitely no changing bases around on painted models! I guess my Ogres will end up as a "casual AoS army", since I like the option to field them in WHF as well - and round bases in WHF are something I avoid whenever possible.
To be honest: I have so many Ogre models, I might do both in the end...
Not true for Ogres, at least not for the infantry. Almost all of them come on 40mm squares for WHF, and 40mm rounds for AoS - so on square bases they are actually at a disadvantage. Cavalry - on the oval bases - should work out similarly, but I never thought about those too much.
Good to hear, thanks for the detailed response! Sound to me like both versions of the Hunter have their pros and cons, none being the strictly better option. Excellent!
