Just a quick opinion of mine...
One major thing this game lacks of is repeating the role classes....
All is great for the PVP rebalancing, but no one is really thinking about the PVM here...
For instance....
We NEED a tank but we ONLY have Enforcers
We NEED heals but we can only do it with DoCs...
We NEED great debuffs and Crowd Control, but we can only do it or it´s best to do it with Crats....
We NEED a backup tanking profession, doesnt need to have the massive HP enfos have, but a secondary profession that could AOE taunt with minor HP benefits, doesnt need to be an enforcer clone...
I´m not going to explain what we need, doesn´t need to be a genious to get the basic concept of this topic...
One of each roles just doesnt cut it anymore... We need a secondary Enforcer, we need a secondary doctor and we need a secondary Crat.
