Like hell she is. Right now, her auto is next to pointless, and with the best refess metas being defined by high agility units (Judie+Verlaat, three buncles at agi 4+, SK0), and one buncle and SK0 that completely wipe out front-row defense, there is no reason whatsoever for anyone to play EXLap meta. Oh, and I forgot, Jack. If you want to slow roll, you can go with mid refess, which is just plop and win unless an SK0 owns you. Heck, I'm starting to think that in this environment, even the old Kaldrao+old Lapierre would be fair, with Refess taking on Gowen's old schtick of mids and high agility low level rushes, Lawtia being Lawtia, and Falkow being serpent and pirates.
So far, for 5 sets, there hasn't been a unit released that's made the justification that EXLap had to lose her heal. And I don't think there ever really will be, because there's only so much you can do with a level 3 agi 2- unit.
