Too much retreat time. Turn time could be lower too.
Retreat time is fine, same as Roper, it gives time to travel to another hide if you are quick enough, the main focus of this scheme is the skill in hitting your opponent and finding a nice hide to avoid getting hit, who can do the most damage consistently? Will you do basic shots doing average damage or risky shots that could miss or do full damage. You might want to travel far away to a hide they will reach fast but could struggle to hit well
The turn time is fine also, as previously explained, most games are focused on hitting well and hiding well, if there was less turn time it would be impossible to reach crates on the other side of the map and get back in time to hit, especially with some of the hides, which keeps the scheme more focused on skill/tactics.
You have to play this scheme a few times to see what is possible and why the settings are what they are, it's about 10 years old and the only thing that has changed is you are allowed to pile now since we have /rs these days.
If you lower the turntime/retreat time, you will find the scheme starts leaning more towards luck based who gets better crates rather than who can fly and attack best.
