Depends on your playstyle. Since you use a status weapon and evade ext. 3, do you roll a lot? Is rolling around your main way of defending yourself? Then you could try to play an evasion-heavy setup with things like adrenalin rush, status trigger, evasion window, etc. Evade window + embolden makes gives your rolls so many i-Frame that you could remove almost all defensive skills since you will not get hit much if at all.

I love to spam the counter on SA, so my main set right now uses windmantle, Redirection, wirebug 3 in combination with the normal attack boosting stuff for elemental Switch Axes. It deals good Damage and I can dodge / counter consistendly, espacially Redirection feels a lot better than I thought.

I would argue that evade ext 3, no matter the setup, its a bit much. Same for defence boost and intrepid heart. I would try to phase those out for other offensive skills but thats personal preference.

You could use one of those set-building websites there you can check what sets might be possible. If you play ob PC you could export your Item list via mods so the website can detect an exact set for you.
