Right! NO previous version of D&D had characters with pets! This is clearly STRAIGHT from videogames!
Sure they did, and before I continue I think literature and D&D has had much more impact on WOW and other games then those games have had on any version of D&D.
Ok,
Name Warlock=same as that of the class in WOW.
Targets a creature and if kills it then is rewarded with a Boon of Souls=killing a target and making a soul shard from WOW.
Those two things alone are not that bad, add in having a summonable pet (Imp, Succubus, ect...) is just so much like the WOW version of warlock to not be a complete and cheap copy.
I would figure that the design team had more creative talents then to just photocopy stuff from the video game they probably play all day at work when they should be coming up with better stuff then what I've seen so far with this current Warlock.
Umm. I'll bet you an imaginary cookie that different warlocks with different patrons have different powers.
I guess we will have to wait and see, but I doubt it. The whole Shadow and Feral stuff is just like the fluff text from the 3.5 Warlock where it can be from any Outsider....but all the powers and abilities had strong infernal influence.
Don't get me wrong as an NPC class or as a class from a splat book that doesn't take up space in the first PHB and limit the available stuff from the SRD the warlock is a fine addition to the game. But has a very dark feel to it, in a game where you are supposed to be part of the points of light in darkness, and a more traditional class like Druid or Bard would be better for the core PHB.
