@wdg96 I'm sorry if you found my reply confusing. You are suggesting the "Join" button be changed to "Lock-In." That is not a bug - that is a suggestion you are making what you believe will improve the game. Suggestions for improvements belong at the main forums.
https://forums.galaxy-of-heroes.starwars.ea.com/categories/feedback-homeHowever, consider a player who goes to the menu and sees "lock-in" - might they assume the game has automatically signed them up for the territory war? Having the button just indicate "lock in" could lead to a different type of player confusion, resulting in players not joining the territory war at all!
Unfortunately, as the game becomes more complicated, the devs always have to balance out tooltips and where information can be found in game. This change to the timing of player lock was a significant change, and they made a specific forum announcement to highlight the change and educate the players.
Currently the system is not "broken as designed." Your opinion is that the design could be improved, but the roster lock function is currently working as designed, therefore it is not broken.
I highly recommend that all players read any announcements and patch notes published by the studio on the main forums. Knowledge is power, and your not knowing this change obviously put you at a disadvantage.
