Of those three, I’d give them to Frida. Aegir is a good tank, but not as versatile, and you already have Oatmeal and Kunchen as possible tanks. Richard is just lackluster compared to the other two
Oatmeal… lol. I will put my vote on Frida as well. My reason being is that you fight titans everyday. So, this should be your number 1 leveling motivator.
From those three You have Frida is probably the best option. She will be nice addition to Your offence (raids, wars, titans) and defence as well.
Aegir after the recent changes is definitely worth ascending as well. Especially when it comes to using him in wars and raids. You just need to wait for the next 6 scopes
I’m facing the same question but between Aegir and Isarina. I’m facing a lot of Aegir tanks at war and he’s very tough. I won’t be using him for war anytime soon though so I’m leaning towards Isarina.
She’s very slow but in situations like titans and quests where I can feed her mana pots, she can be deadly.
