DUDE, so fucking sick of seeing people complain about it being "The Brendon Show". Spencer had a good head on his shoulders and told everyone what was going on and they had a solid plan B that took care of the fact that he won't be there. Dallon said he and Brendan weren't comfortable with drawing attention to spencer not being there, by it just being brendon it's not such a big deal. He's the only other original member. If they went with the spencer inclusive promo material it would just make it seem that much more exploitative.
I think the evidence is that Spencer not being there has drawn a lot of attention, hence you needing to reply in their defence.
That said, I hope Spencer gets better and I'm sure they're not secretly phasing him out as part of some master plan. Look forward to his recovery.
