To delete or not to delete?

Hey guys, my account was finally unbanned today, and I'm semi-eager to try out the new classes. I have 20 characters and no extra slots. I was wondering if I should delete my Mihile to create a DW, which I will use to get the hat and extra character slot tomorrow. I don't like Mihile's play-style, although I haven't played since release. I do think his link is useful for characters with no stance, such as my BM, but I find myself just not using it, or even forgetting it is even there at times. It is currently level 156 with no special gear, as all I use is tradeable %str gear. Or should I leave it be and only use the slot tomorrow to make one of the koc classes and obtain the DW hat on a character that won't even use it?

I'm leaning towards deleting, but I've always had this thing about deleting characters. It just kind of makes me sad
