Except this attempt at an analogy doesn't work because your rebuttal has always hinged on only "veteran raiders!" being able to play healers at such a level to achieve high DPS when the reality is even a decently average player can easily complete even the likes of Savage with little to zero GCD heals. What Xeno did that sparked this whole strike wasn't some impressive and difficult feat but rather easy to do because of the paltry amount of outgoing damage. When leveling Viper and Picto together with a friend, we had another friend go tank who literally just got his first tank (Warrior) to 80 before DT dropped yet here he was doing 3 DPS and 1 tank runs, full wall pulling without any issue.
Now you can still like the design for its ease and simplicity but it's undeniable at this point that healers can be made easily redundant even with only a decent tank so long as they know what CDs are. No matter what your preferences are, that simply isn't good design--especially not in a trinity system.
