FTL in Classic / Setting up now and use when it goes live

[Perrigrin]

I've been setting up the 2 teams I wanna run, using new characters on live servers and following the PRO method (I'm new to that, but old to ISBoxer and Boxing).

Now last night I started watching Mirai's new video. While covering the wizard - I think he says that FTL wont work in Classic.

1) Does this mean that my PRO setup team I have created, will not assist and follow properly? (I'm pretty sure I left the FTL at whatever option is default)

2) If that's the case, how do I mitigate that - What do I need to fix?

I definitely didn't say that.

What we've been saying (for months), is that everything in the macro API, outside of focus, should be exactly the same between the two games. What we've also been telling people is that Vanilla is not Classic, because they wanted to "practice" for Classic and the macro API is much different between those two games.

So Classic won’t have the old school version of /castrandom? That’s too bad, was hoping to take advantage of that
