OP, I don’t know you - is your four star bench already solid? Because if not then working on this is the clear answer.
I have Santa and GM, but not JF. I realize that GM is not a perfect analog, but it’s the best information I have to offer. GM is WAY better than Santa. To such an extent that if JF is some reasonable facsimile of GM he’d be the clear call for me (that is, GM is so much better that an 80% GM would still be > Santa imo). I think JF is interesting and am hoping to still land one in the Costume Portal. I face a lot of Kunchens and Finleys, so his pre-buff defensive flip looks intriguing.
Really? I’ve only run into him a couple of times. Realizing this may be slightly off topic, but are other people seeing him much in the mid or high Diamond Arena? I don’t think it’s totally off topic, because his presence there (or lack thereof) will say a lot about what most of the game’s elite think about him as a defender and whether or not he’s worthy of emblems (since, if he IS showing up near the top he will undoubtedly have emblems).
Also, if he IS getting emblems at that level I think it’d be very telling, as this would be the group most likely to have Hel / Guinevere / Zeline. If he’s getting fed in conjunction with or instead of that group then we can also infer a lot about his perceived worth from that.
