There's a lot of stuff other characters just have to hold, like Cammy's divekick during Trigger, Bison's EX Devil's Revers, Rashid pressure etc. that Falke can just blow through with EX DP while blocking. The last part in particular is huge. And as slow as it might be, it can still work as a deterrent. Simply having a reversal is sometimes better than using it. Plus the usual V-Reversal and V-Shift shenanigans, because let's be honest, Falke doesn't really rely on her Triggers too much.
I rarely felt threatened in the Cammy matchup with Falke for example, whereas I'm almost applauding Rose for not committing suicide on the VS screen when I run into her.
As for Rose's Triggers, I'm not sure what to think of yet. Illusion is definitely better on paper, but you absolutely need to hit-confirm it or AA with it. Which I'm too bad to do consistently. Teleport at least gives you some value when you activate it off a blocked sweep for example. You can do a little Dhalsim mixup or make a dumb EX Drill safe or something. If you activate Illusion on sweep your opponent will just block it out or not quick rise (if the sweep hits) at which point it will have drained by 50% already. So yeah, great Trigger for great players. I'll noob around with Teleport for the time being.
