They're doing a better job of interacting with the community on their reworks, or at least being transparent about it. But nothing in that thread makes me think that they aren't just pulling out something wacky because his kit is a pain to balance from a "fun" perspective.
The idea of "talon's identity is roaming" is ridiculous. It's another iteration of their heavy-handed and ultimately untenable approach to giving champions extremely discrete identities. In that very thread there is an excellent rebuttal to the idea that talon's identity is roaming. Apparently, it was ignored.
I'm not saying what they have in store won't be pretty cool. Maybe it will. It sure sounds neat, and they can barely keep it together with how excited they are, constantly alluding to it and all. But nothing said there makes me think that Riot doesn't (correctly) think Talon's kit is horrendous to try to balance from a fun/interactive gameplay perspective, or that they decided to go someplace weird with his rework because there's no place else to go.
