Yeah I gave up on elite streak, although got the hard streak going. I'm currently somewhere on lvl 16 (rank 78 or 79) so still got a way to go, but I've enjoyed taking Zillee through it and will consider TRing her again.
Just started a monk toon and am loving it, so maybe her next life will be monk. Want to try and take the new toon a bit further first though to make sure I'll like it enough to see it through, but that would mean two fighter past lifes for her monk life which I believe is +2 to hit and her tactical DCs.
