Thanks for the assistance Yabooer. I do appreciate it, and am glad (as well as surprised) that you've taken the time to read and learn everything about the mod so far.
Now to help answer both Yabooer's questions and Crillepro's:
YABOOER:
1. Well due to my memory becoming increasingly vague on how the original World of Warcraft worked (it has been about five years now or so I believe since the original's release) so I can't get it all right, plus, many of the changes in the expansions helped make the game much more convenient and overall a more enjoyable experience. But obviously not all expansion content will be added. For example, I believe that getting your first mount at level 20 is unnecessary for Wc3:WoW because there are only 60 levels, it's much
easier faster to level in Wc3:WoW than in WoW, and so level 40 mounts make more sense. Plus, the world is smaller in Wc3:WoW, so traveling will generally be faster than if you were in the real World of Warcraft.
In short, playing Wc3:WoW will be very much like you were playing the original World of Warcraft. But there will be some drastic changes to it most likely some day (I plan on adding some insane Realm Versus Realm systems in to stir up the action in the game) but none from any expansions, unless both the team and the community agreed that an expansion idea was good and fitting enough for the mod too.
2. Yes,
some weapons and armor pieces
will use the same textures. Mainly in-game textures though will be reused, for the sake of optimization of file size of Wc3:WoW and to save the team some time. Many weapons and armors will have unique textures. Some even may use a mixture of in-game textures and custom ones.
3. You're somewhat right with the percentages. But we can't allow them to think like robots the entire time - they need an instinct, so to speak, that helps them react appropriately for dire situations that put their robotic strategies in jeopardy. So sure, they can let the Mage die accidentally, but saving the healer or tank with some last-minute heals or pulling aggro quickly will help more than just to stick to this target, then move to the next, then the next. They should learn to switch between targets, especially when there's more than two targets. Such intelligence will make them work more intelligently and professionally in PvP as well. If you can't already tell, I'm super excited to get bots working with PvP (and good at it both with you and against you).
CRILLEPRO:
1. Explaining how bots work in instances is complicated and difficult, especially since we haven't started on doing A.I. or bots again just yet. However, bots will be intelligent and dumb. There will actually be a percentage chance (or so I'd like to include in Wc3:WoW) that determines which bots are smart and good, and which are just bad at the game. This is for balance though, especially for PvP. No one wants to play Wc3:WoW and feel like they're being raped by complete experts. Some bots will be really damn good, but others will be so easy to dominate, even a caveman can do it!

So I cannot answer this question fully until we start on bots and their artificial intelligence.
2. To elaborate more on how bots will work, basically, is each class has a few roles. Though it depends on their talent-tree build, tank classes know to tank and hold all aggro, healers know who to heal, and dps knows what targets to assist. Sounds perfect, but it's not. With the mixture of dumb and smart bots, this should make the instance run rather interestingly, making you worried if the hunter in your group will send his pet after that giant mob of there, or if the warrior will Charge the boss before the casters have regenerated, or if the Rogue saps the wrong (or fails to sap at all and is seen in stealth) mob and gets killed by the tougher guy. I'll be fun playtesting, I'm sure. And it'll be a wonderful addition to Wc3:WoW that helps define why it is so great.
3. Will they act like real players? Yes and no. You can't predict every situation in the game. No one can. And with such a small team, we probably won't get too far into such a process unfortunately. But we will try to make them act as human as we can. Working on communication skills and diversifying them will help with that a lot, but I'd hate to have it be like one of those games where you can learn and get used to every dialogue in the game from friendly bots within a day. So expanding the communication (AFTER how they act, such as what they target and do, like jumping around) is definitely something I'd like to have us explore in the future of this mod's development. Though, it is something that technically is impossible to 'complete', due to the vastness of the idea.
4. Will there be instances? Uh, yeah. Obviously. But the only playable one in 2.0 will be Ragefire Chasm.

1. It's a mixture of three things. The Hive Workshop, WarCraft III, and Exclusives. Meaning, a lot of models and textures are already from WarCraft III, untouched (or maybe the texture is modified a tad), from Hive Workshop's models and skins section, and of course our dedicated modelers and texture artists do some great work that only the Wc3:WoW team and not the public have access to.
