Why is marth so underrated ?

Any unit could be made viable from skill inheritance, and Marth is no different. (Aside from the heroes with really unbalanced stats)

powercreep is why lmao

He doesn't really stand out is why. Joshua is basically Marth with lots of RES and far better skills, so for tanky swords you would go Joshua. For offensive swords you would go have Ayra who has the same HP, slightly higher Defense, better offensive stats, and far better skills. All for the cost of 2 res. Long story short, Sword units face very tough competition. For any build you set Marth to there is pretty much another sword that will do it better due to being better min-maxed, having stat boosts, or simply having flat out better skills. If memory serves the only area he really stands out in is being the best Falchion Medic and the others are close enough that this isn't huge

To me, what makes Marth stand out is that he is available at 4 star and I am close to 10 marge him. He really likes me a lot......
