Considering all the code that was directly taken from WoW, I think it's safe to say this is a WoW re-skin. Plot and Lore in this game is piss poor. The replayability is basically zero. The created like 8 zones and have you replay them 4 times. Yeah, I can sense a lot of effort was put into this...I can't entirely blame Blizzard, I'd wager a good bit of of it is Activision telling them they need to release by such and such a date. But since WoW started Blizzard has slipped from their legacy of releasing largely polished games like Warcraft 1-3, Diablo 1-2. I would imagine I could list many more things, but I haven't played WoW in about 7 years so I can only comment on beta WoW and the first year prior to Burning Crusade.
I can see how some might make sense, but you're really grasping for straws with half of these "similarities". Let's begin:
-Log-in system is from WoW.
-Main character screen and buttons/menus are from WoW.
These two - Are you serious? How on earth does this affect gameplay? Just sounds like you needed something to whine about here.
-Weapon system is from WoW.
You'll need reasoning to back this up. The weapon system is exactly like D2. Can you tell me where in WoW there is Magic Find? And how this magic find actually affects other items? It is non existent, other than you trying to throw a blanket over it. I could argue that WoW took from D2 using your logic.
-Classes are renames of WoW classes (Witch doctor = Warlock, Wizard = Mage, Demon
Hunter = Hunter, Barbarian = Warrior, Monk = Paladin)
This is another grasping for straws. The Wizard, Barbarian and Demon Hunter have been in all 3 Diablo games in some fashion, the Witch Doctor is the spinoff from Necromancer and Monk is not even close to a Paladin. Have you even played all these games? Again, I could argue WoW stole them from Diablo 1 & 2 using your logic. Which I wouldn't.
-End game of WoW is basically Diablo 3, grind for marginally better weapons and armor so you can start farming the next boss
What loot based game isn't? Diablo 2 was the same, as was Diablo 1.
-The fonts, UI, colors, character models, etc are all very WoW.
I can't believe you think statements like this are a valid reason for anything. Should they just not have fonts, UI's or colors? The character models are much more detailed than WoW models, even so - should the characters be invisible? Show me a side by side of all the classes and their respective models in WoW, until then you're just whining.
-The leveling system is direct from WoW (even the initial level cap from WoW at 60)
The leveling system is standard for most RPG's of this type today. The level cap is arbitrary. The fact that it is level 60 does not make it like WoW considering the stats and strengths at level 60 in Diablo are much higher than you were in WoW. Again, did you even play WoW?
-The AH is from WoW ( though strangely worse then WoW, not sure why they didn't copy it verbatim considering all the things they did)
Again, just more whining. How different do you expect an AH interface to look like? Also show me in WoW where I can break it down by stats on the item, even though I think this is a stupid point anyway.
-Skill system is WoW trees minus the trees , where only one or two combination are viable at the end a la frost mage from WoW.
This is the case for most games with a variety of options. The highest DPS will come from one specific combination. Diablo 3 is the first that I'm aware of to try and ween away from this - give it time and I don't think your argument will stand with even the minimal legs it has to stand on right now.
-Annoyingly incrementing revive timers
-Enrage timers for bosses
This is the one or 2 points I might fully agree with, however these are there for a good reason. If you don't like incrementing revive timers, quit dying.
-Color scheme of weapons and armor
Again, try my challenge to this point as stated earlier. Additionally, it would make sense that armor only has so much variety. Please, use your artistry abilities and come up with something better.
