Has Blizz every considered seperating PvE from PvP aspects of the game? A lot of balance problems seem to come from one ability being too powerful in PvP but the resultant nerf in PvE causes additional problems.
If we're talking about making spells work differently against players and mobs, then yes, Blizzard has considered it, but the developer response on the topic has nearly always been that they feel it would make the game too complicated for new players. This is, of course, ignoring the fact that several abilities already work this way.
If your question is "Has Blizzard considered completely separating the PVE game from the PVP game?" -- well, I certainly hope not. It's good for players to have a bevy of possible play options available, though it's certainly problematic that one just will not stop damaging another.
With the new 1-60 content, and revamps of lower instances into 5-man heroics, and former raids becoming 5-man heroics.. was there ever any inkling of new lower instances? Something in the 15-50 level range. Not a revamp, like we've seen with the quest givers standing at the front, or the WC map being easier to follow, but something completely new.. that would make leveling alts a little more interesting. This would probably take a lot of work, and well as story work-around, which is probably why it hasn't been done. I just think it'd be a neat thing to ponder.
This is unlikely, only because there are already a ton of low-level instances and the time spent while leveling from, say, 30-35 is nothing compared to the amount of time you spend at max level. Cataclysm gave 1-60 Azeroth a makeover; I wouldn't expect much more for a very long time.
How constrained are the game designers by lore? For example, if they thought they could make a compelling and unique bard class, would that be a no-go because there weren't any bards (to my knowledge at least) in previous Warcraft games or established in lore, or do they have the leeway to either retcon the lore or say "They were there all along, they just weren't mentioned"?
In other words, if we haven't heard of an entity up to now in previous Blizzard content, does that mean we're almost certain not to see it as a class or other type of gameplay hook?
Good question, but we've already seen the answer. If Blizzard needs to invent new lore from whole cloth to make something work, it will. We'd almost certainly run out of stuff to see in Azeroth if a story hook had to already exist for something to be added to the game. We're already rapidly reaching the end of available lore characters, zones, and villains from older Warcraft games. New blood is okay, as long as it works.
