Lucina is not one of my top picks personally. She's sweet and she means well and I like her but she's not a favorite of mine. I'll go with you on Ike but I'd dispute Chrom and Eliwood because both of them are a bit soft when it comes to hard choices. They wouldn't sacrifice the needs of the few for the many if it came down to it. But that's also disputable. I can't agree on Sigurd because just like say Alm I don't know much about him but I'll give props to Marth he was a genuine badass to do all he did just like most FE lords.
