The issue nobody wants to address

I wonder, if as healer or tank, I let the group die a few times, because you know, thats how my playstyle works(I pay my own sub,right), how annoyed would any of those, "dps play how they like" players get.

I'd say it's a lot different, though equal in theory lol. Unless the bad DPS are leading to wipes, it's not really on-par with intentionally letting your group die and start over. That's far more along the lines to griefing than some DPS (un)intentionally making it longer, without causing a reset of a fight to occur. Bad DPS will eventually get you there without having to start over because of wipes, exceptions being DPS checks. It's not an equal situation between the two (three if including tanks), despite what people want to think of it as.

Tanks and healers have more responsibility by a default. That is, unless each and every fight in the game, including trash pulls, involves a situation where each DPS is held accountable or else they wipe the entire group, similar to a bad healer or tank. Maybe something happens to each party member and they are separated or incapacitated, so each DPS has to do X amount of damage quickly or it's a wipe. The frustration and anger by the player base would be HEAVEN to sadists like myself. Exponentially so, at least for a good while, than simply letting your group die a few times. Oh please let that accountability be a thing!

Edit: Can't help but think about the crying to result from that. Not just the bads crying, but even the people who wanted equal accountability. Being unable to use DF to clear daily roulette as reliably as it is now because groups can't even clear trash. It's so good from my own entertainment perspective lol. I don't really run stuff very much, so it'd hardly affect me. 24-man raid ease would be, probably, the most unsuccessfully cleared content lol. Unfortunately, that'd probably only be a huge deal during the first few months, as any remaining players would have probably adjusted or already been good enough to do these things.
