Agreed, being tied with Keiran, losing availability, and generally being close to the team should not warrent mid.
I mean, Eddie has availability, and at a time can actually claim he's the best of the team, while still being useful for a few more chapters. I mean, that sounds about right, doesn't it, about equal?
Wait, no it doesn't. Eddie's got availability, and actual utility on Geoffery, while Geoff is just Keiran without the availability. These guys have 2 chapters of good (like Eddie), 1 chapter of meh (like Eddie, in the form of 1-5 of which you don't have to field him, unlike the CRK). However, Eddie's still got 1-4 and is still ok for 1-2 and 3. Keiran after his good time comes to the merc, where he shows that he's hot garbage, something Geoffery deals with far later in the game.
Geoff can fall to lower mid, but Eddie does not deserve to be there with him. Raise him to the bottom of mid, and I'll be fine with it.
