Well I completely understand the priority of including Rogue One heroes first - hopefully drawing in new fans, giving us more options etc - and not oversaturating the game's number of people to farm at once... I am really wondering when the game is going to balance out a bit?
I mean we have 4 Ewoks, 1 Wookie, hardly any Empire and yet Rebel options are absolutely incredible. A lack of Sith is always understandable due to their numbers being low after KOTOR era, yet there are still so many untapped options. Wookie slave perhaps for Empire as an option to boost both teams (Wookies & Empire) etc.
It'd just be real nice to see an inclusion from each movie/game every month/two, rather than 4-5 Rebels a month. Particularly considering the Rebel team is already excessively strong, so anyone new that is worthwhile makes them even more unbalanced, while anyone else is almost pointless.
