Ok,here is the view of a very low mmr player.
i realy enjoy ranked. Why? because it feels like you can learn a lot about positioning, when to stagger etc.
In the beginning as order healer i could play 4 matches in a hour, and i played about 20 games. I lose 16 and won 4. 
In these 5 hours of gameplay i got 211 Triumphant emblems, and the costs for equipment go from 1518 for belt to 4576 for chest.
So it takes me 40 hours of ranked queuing for the belt, and 108 hours for the chest.  
 
 
But at the moment i just dont get any pops with my insane mmr of 1203 as a order healer. Yesterday i saw Zarbix queuing, and tried it too. The time he played 3 ranked as destro i got 1 pop but the match did not start.
next problem balancing in low mmr. After some matches i startet to take screenshots after each match.
and here are the numbers:
  Win           Damage               Heal                  MMR          
             Destro  Order     Destro  Order     Destro  Order   
Destro    419k    370k       346k     330k      8601     7657      
Destro    296k    131k       180k     238k      8963     7934
Destro    288k    148k       147k     225k      10021   8715
Destro    419k    370k       346k     330k      8601     7657
Destro    153k    111k       72k       111k      8536     7763
Destro    247k    106k       95k       227k      7855     6534     (5 vs 5 match)
Destro    359k    255k       252k     308k      8878     8192
Destro    964k    347k       382k     882k      8915     7866     (2 shield tanks)
Order     142k    252k       198k     149k      8274     8077
                                        Average
             354k    232k        224k    311k      8738     7844     
                                                               
And when i take a look at the bottom of the 6 vs 6 leaderboard at the moment, there are only 3 Destro players with an mmr below 1400.
So, do i enjoy it? YES
Is it worth the time equipment wise? Sure not
Will i play it? Yes, but at the moment its not possible, because i get no pops.
