How many Rigards should I keep?

So, I’ve been fortunate enough to acquire 5 Rigards…how many of them do I keep?

I know/see that Rigard is still used by many high level players, so I know he holds his value and I have his costume. I’m just not sure if I will need 5 of him. Thoughts?

I think the answer is all of them, but roster space is QUICKLY becoming an issue

I have other healers too: Kiril, Melendor x 2, and Hawkmoon x 2

I appreciate your input and opinions.

Thanks
