In these scenarios where the damage gets completely out of control, Bless is not the problem. The -5/+10 from GWM or SS is the one piece that makes it all possible.
For example, take the level 11 case from the table I posted earlier. An 11th-level archer fighter shooting at a medium-AC target (AC 16) with Crossbow Expert, Sharpshooter, Bless, and Advantage deals an average of 67.3 damage per round, compared to baseline archer damage of 23.5. Almost triple the damage.
So of those four things stacked together to create massive damage (CE, SS, Bless, Adv), how much do they each contribute? One way to look at it is: If you remove any one element, how much of the extra damage goes away?
The damage drops by a decent chunk when removing any of the elements, but Bless is clearly the least important contributor to the damage, and SS is by far the most important contributor. Without SS, about 3/4 of the extra damage goes away. And this is only considering the -5/+10 component of SS; it would be even larger if ignoring cover or range penalties came into play.Code:Damage Decrease in extra damage All bonuses 67.3 0% All except Bless 60.4 16% All except CE 53.5 32% All except Advantage 50.7 38% All except SS 35.0 74% No bonuses 23.5 100%
Your analysis is biased towards a certain outcome. It can be biased to highlight other components by altering the situation. For example, here's that same analysis with stacked Crossbow Expert, Sharpshooter, Bless, Advantage (Faerie Fire), and Purple Worm Poison, going up against a Beholder (AC 18, Con save +4). A beholder is a target that is absolutely worth spending 2500 gold on to kill safely, especially a whole shipful of beholders, so purple worm poison makes perfect sense. Under these conditions, Sharpshooter is the most insignificant element of the combination. The venom is of course the most potent element, but advantage and crossbow expert are nearly as important.

This once again highlights the fact that Sharpshooter is famous not for being especially strong, but for being cheap and readily-available, and also having nice synergies (ignoring cover and range are very nice). But in any fight which is actually important, there are better ways to spend your resources than on buffing the Sharpshooter to twice normal DPR.
