Guild Wars 2

Some people like alts, some people may have deleted their SAB character, some people may want to have all their characters expierience SAB, well they can but you’ll have to start from world 1 with no tools.

I can understand it was characterbound may have been because somebody could alt farm in some way accessing the easiest worlds. Well now that chests are daily that wouldnt be a problem.

I think once you have a world unlocked, or an item bought all characters get it, excluding maybe potions or something.

Also you could play another character, not your SAB character who just happens to have 20h of Birthday Boost left.
