I think it's okay to leave it in the scheme. There are very few instances where it leads to a huge advantage. Also, since it is an aerial weapon it cannot even be used for 2/5 of the games, so that makes it less valuable.
FYI: I solved my issue about not being able to watch replays. The 3.7.2.1 option of "load wormkit modules" was NOT selected. I selected this option, and now it works. I also don't call wa.exe through WormKit.exe anymore. I don't think this is related, though.
