Nope, and don't intend to. She's not as flat out dull as Hayate/Hayabusa, but her constant Pyrrha-style whining about not wanting to fight is really irritating. Seriously, not interested in the ninjas. Any of them.
I've been playing Hitomi a bit, and she's actually starting to seem like a less dynamic version of Ein. I never noticed her voice much before, but now actually playing her and listening to it every match, I'm not sure if I can put up with it! Still, it's nice being able to actually get involved in the fight; Tina was always pretty disconnected from the action. Just defend as best you can and try to get an opening right.
I really like Nyotengu; she's dramatic and theatrical, and has some really spectacular combos, but I'm not entirely sure her terrible neutral game and slow speed gets me away from the whole 'guess right' meta that's making me reconsider Tina.
I quite like the look of Rachel, but she doesn't really seem to have an awful lot of variety. Even tourney vids of her just seem to be the same few strings repeated.
Kind'a wish TN were just a bit more active in terms of patches, most of it just seems to be very minor, obscure changes that don't really affect the character. Hell, I think the most Tina's ever gotten are some additional camera angles on some of her throws and some minor changes to moves that don't get used... Tina could use an OH that actually works to deter people from just hammering into her constantly, or at least some better hitboxes and frames on some of her pokes. And Nyo could use a damage buff, as a tengu she should hit like a truck, but her damage is pretty crappy.
Still, I'm enjoying the game far more than a I have in a long time. A lot of the flaws I had thought were the game's problem are actually just Tina's. For example, I'm a long-time SF player, and I was always a character specialist there, too. And despite focusing on one character, I learned how everyone else worked just by fighting against them, and I never found that to be the case with DoA5; no matter how long I played, I never really got much understanding of how other characters worked. I'd thought DoA5 was at fault, but after playing Hitomi for a while, I now realise it's actually Tina that's to blame. Tina's so removed from the fight, and her moveset is just so bad for anything other than dealing actual damage that you never experience much interaction with the other characters, and never learn how they work by comparison with your own moves.
So as much as I enjoy playing Tina, she kind'a screws my ability to enjoy the game. I don't think I'm alone here, either; the game's still active, as are these forums, but Tina's forum is pretty dead and you never see her in tourneys any more, despite being generally ranked mid.
Yes, this was my attempt to steer the topic back to being about Tina and to avoid my inadvertent highjacking. Whoops.
