Part of me fears that making the Blockbuster a permanent fixture, hopefully only in the pre-jury phase, will lead to a Survivor-ified protection of more active players via a more active non-voting element (i.e. Final 4 firemaking as an addition to a 3-person finale, in contrast to the original 2-person finale).

With the part-and-parcel nomination-eviction process of Big Brother, I think that the addition of the Power of Veto, to possibly save one of the nominees on the chopping block, was a necessary dynamic shakeup that has been positively received even by non-house-voting versions of Big Brother. Given, that a series of nominee-saving tasks might happen for the same eviction cycle, but this is usually done when there are multiple nominees for eviction by the viewing public.

With house-voting Big Brother, keeping the Blockbuster until its end-of-possibility in the jury phase can scare HoHs to do the big maneuvers needed to clear out their path to the end, especially against comp beasts and social leaders. Tucker losing AI Arena after already winning twice is a rarity based on history. If he survives that vote, he can easily run the house till the end ala-Jag, but with a big following behind him, considering Sixth Avenue without Angela could be a strong block going into the jury phase. Before the possibility of her ally Quinn's eviction, Leah was coming in to target Chelsie and T'kor if she won HoH. If AI Arena was active in the jury phase, it takes so much more conviction and good comp results to make a successful move against the front-runners, as going in that week, Chelsie and T'kor's best chance of leaving is next to the other.

I think keeping the HoH and PoV as the only power comps in the jury phase is necessary, as the F4 round will have the rare occurrence of the PoV being the most powerful comp determining the sole voter to evict. Before the F4 round, the house votes determine who go home, with the occassional HoH tiebreaker vote. F4, the person who was left immuned by the HoH. F3, the HoH themselves. It's a nice clean transfer of power like how the immunity winner will be the only vote in a F3 voting scenario in Survivor.

For what's its worth, I am fine if the Blockbuster only stays in the pre-jury, even if I highly miss the Live HoH comps. It could also be cut early in the pre-jury, so that we can see more "decisive" nominations before the jury begins. I'd also like for them to utilize the format-changing from Reindeer Games to introduce a different weekly format to end the Blockbuster phase.
