Can an expansion survive without a DPS?

[ThaCa]

Basically the title
Can an expansion survive without a DPS as one of the new jobs? -Not counting limited jobs

Looking back at past expansions there always has been a DPS as one of the new jobs

HW introduced DRK and MCH
SB had both SAM and RDM
SHB had GNB and DNC
EW RPR and SGE
And now DT will feature another 2 DPS Viper and Picto

You guys think if we ever got 2 supports (say 1 tank-1 healer, 2 tanks or 2 healers) could an expansion survive the hype?

Expansion would thrive if they actually made Tanks and Healers even half as fun as DPS.
