The new gear system in which the primary stats change to the spec meaning that all hybrid classes can only need one set of gear for all of their specs, This may mean that it is more beneficial for raiders to go play hybrids of over pure classes. Hybrids do similar damage to pure classes with the addition of extra utility and healing.
Personally with this change I would be better off playing a class like druid over my main Warlock since I can change specs depending on the fight I can be moonkin if the boss favors ranged dps and feral if it favors melee dps. I can also have the option of switching between resto/gaurdian if any of our healers cant attend the raid.
What is the benefit of this system for pure dps classes ?
