True and I'm grateful she got one at all, unlike Trish/Chun-Li/Cap/Parker. However the truth is that OTG capable moves are pretty much the most desired property in a move right now due to the fact that there are so many unrecoverable knockdowns in this game, and they can be used as many times as you want in a combo, unlike ground/wall bounces. Having crappy OTG moves doesn't quite condemn a character to Rolltier, but it does cripple them somewhat. Not being able to do much after an air throw is a pretty big disadvantage in my book. And the fact that there are only so many OTG capable assists, and characters like Cap and Parker are downright crippled when paired up with certain characters. Trish and Chun are saved from this because their combos are mainly aerial based and lack of an OTG doen't really affect their gameplan. Still seeing a Chun throw someone and standing there because she has no OTG assist or move is jarring, especially knowing that Storm can fucking DHC glitch from a throw and can outright kill a character.
With a good OTG move, you can call almost any assist and combo off of that. With a great OTG move you can continue the combo after that by yourself. No OTG move and you're forced to rely on a OTG capable assist, of which there are limited numbers of. Honestly, Wesker, and Dante wouldn't be so feared if they lost the OTG property on Samurai Edge/Volcano/Wild Stomp.
Some characters of course do well without OTG moves. Chun and Trish are examples. However their gameplan is different. Chun is more aerial based, and Trish is more keepaway and aerial. Hopscotch and Peekaboo help with that. As for Chun, most of her moves keep her opponent slightly airborne and her super launches, so not having an OTG move doesn't hurt too bad as well. Storm's fucking awesome OTGs make up for the fact she has no OTG specials or normals. Magneto had one of the best OTG level 3s in the game, and his gameplan also keeps his opponent in the air while he ROMs you to death.
But then we get to Cap/Parker/Joe/Leilei and you can see the lack of a good OTG normal/special really hurts them.
