I would take mage mobility over warlock mobility any day.
None of our defences will is matter if our damage dealing mechanics is vulnerable as it is right now, i can use all my defences and still half brained class will kill me, simply using chain of CC and interrupt when it’s needed.}
Warlocks right now posses big rough damage numbers and zero utility and meanings behind that numbers.
Damage dealing mechanics are boring and some abbilities are simply not designed to be viable in PvP, just look how dreadstalkers work in the dynamic enviroment.
No other class is suffer from bad design in so many design and tech levels of class as a whole as warlocks.
