I think a significant component is that lots of high level players already had her maxed and emblemed heavily - and not many hero’s make a claim to strip them from her…
So she’s there, fully emblemed and staying that way - makes sense to use her?
Purples are indeed a mixed bag defensively…
Seshat is definitely up there with the very best wings and probably the best purple on defence, atleast now…
Ursena and BW do a great job at tank but aren’t nearly as scary anywhere else (Ursena wings seems to be becoming a thing with some people - I just don’t get it, she’s absolutely terrible on the wing!).
Then there’s a bunch that are just average at best on defence despite being excellent elsewhere.
Interestingly, my defence also holds consistently around 2700… but with significantly lower TP (4368).
I wouldn’t bring it up other than as a point of comparison, suggesting that it may be fair to say that you’re right to look into playing with a few changes? With the emblems and bench I suspect you’ve got available, I have no doubts you can be holding noticeably more
I’d consider possibly running Seshat on the left and bringing Drake inwards to flank?
What other blues are on the bench besides Lepus and Fenrir? (I’d try to avoid stripping Zim if possible, attacking cleanse is so nice to have!)
