First of all, sorry for any mistakes you'll find here, english is not my native language.

I got Marr quite a long time ago, and I finally decided to CC / AW her recently. Now she's sitting on her level 90, and she's for sure a goddess for any spirit or DC daily.
But I'm still unsure about whether she should be in my main team or not, cause I dont know if she's that helpful when there is no poison on the map. Her little lack of range and attack (without skill) when compared to silver healers is making me reluctant... What do you think of her, on nutaku or DMM ? Is she worth a permanent slot, or is she a situational unit ?

All my thanks to those who will answer
