I think, that the main problems with tanks appeared on exPrimals, because the previous content was too easy for tanks. Only Coil is hard. But all another content ... What tanks need to do? Just stand, hold agro and thats all. But exPrimals showed, that tanks must not only stay like stupid puppets without a piece of brain, but tanks now need to move and make some another tricks. And we see tanks with wide opened eyes and saying "I need to do more, than just stay? Ohhh... it is so haaard" The best example is exTitan- tanks cant dodge Landslides and cant hold mobs. Very nice example of common tank's low skill level (not all of the tanks, but most of them)
