Temple is tedious, already bored with it before campaign has finished

I've completely stopped entering the temple. Having to clear 6 areas before even getting a chance to enter, building it, then doing it all over again (another 6 maps)... plus the lackluster rewards? Yawn.

I've stopped interacting with it entirely. Scrap this or just let us reenter it right away without having to do 6 maps again.
