What are your thoughts on SS Artemis?

Her Spd cap is awful for a 6* unit, even the normal version has a higher cap, and not as excessively accurate to be reliable with crossbows like her normal version either (not that it matters a lot in PvE, but still) however she is more defensive orientated, and with the Robust Lance skill, she may be decent alongside Axe units, especially against those nasty Sword Absorber - Sword Breaker enemies. Of course I'm not using her in Colliseum/Multiplayer, but still I thought she might be a decent filler for the team. Anyway if you had time to read this guys let me know what you think.
