One thing for you all to consider is that warriors may be worse at some fights but better at others. People have pointed out some fights with heavy constant damage, mentioning that paladin is better suited for this. Yet if a team encounters a hard DPS check, you may see them using a warrior tank because they can handle the (more difficult) healing and need the boost to pass the hurdle using the gear they have. Another example is that some encounters will have infrequent huge spikes of damage, and it becomes a challenge to fill the tank back up in time for the next spike. Warriors may be well suited for this type of encounter as well.

I did speak with someone who is working on turn 2 in coil. He said that paladin does have an advantage for the first turn, but that warrior in his opinion is much stronger in the second one
