Dungeons
From a design perspective, the redesign of Upper Blackrock Spire is a similar challenge to the creation of a new dungeon. While the tower base exists, but Blizzard is not limited to increasing the health and damage monsters. New mechanics may appear and must be given a real challenge to players without losing the nostalgic side that comes when we return in an already played in the past instance. Where Blizzard saves time, it is obviously because the boss and the dungeon itself already exist and it does not need to be created, even if the models are updated.
Raiding
It will now be easier to determine which is the best PvE guild. At present, some guilds are 10 raid and others in raid 25, so it is difficult to say which of Paragon or Method is best. With the mythical raids 20 players, it will be much easier.
The raid Highmaul open after the release of the expansion, probably the second week. As with cellars Mogu'shan in Mists of Pandaria, Blizzard wants players enjoy leveling quietly, without feeling obliged rusher until level 100 to start their raid. Highmaul is located in Nagrand and have 7 bosses.
The raid Blackrock Foundry open a few weeks later with 10 bosses.
When opening a raid, every boss will be available, except in LFR mode where they opened on a specified schedule, like what we have known for the Siege of Orgrimmar for example. Players must first discover the boss with their friends and guild rather than going into LFR.
The most successful Mists of Pandaria boss is in his Lei Shen. The game mechanics are both simple to understand but difficult to counter, it happens a lot of things that make the fight extremely interesting. The team is very proud of this event. We can therefore expect some boss in the same style Warlords of Draenor.
Raids should be less linear than in Mists of Pandaria. The objective is to make a bit like Ulduar, where guilds could choose their boss depending on roster available in the evening. This is feasible in a raid consists of several wings, but not otherwise. Raids Warlords of Draenor should therefore not always be perfectly linear.
The meetings will include a lot more mechanical classes, especially for healers. Care in Mists of Pandaria were not very interesting. In Warlords of Draenor, Blizzard wants to deploy more interesting for mechanical trainers, where their role will not be spamming the same ability all the time. They will select their aptitude and choose the right, at the right time and the right person.
World Bosses
The bosses outside represent the largest and brutal creatures Draenor.
One of them is an ancestor of gronn we know, but like three or four times larger. It is made of stone and will have a mystical power that allows, for example, put his hand on the ground, which will peak out stone floor below his enemies.
The second World Boss will be part of the huge plants that live in a jungle of Draenor.
The World Bosses will be activated gradually, knowing that the first will be the launch of the extension.
Loot will be interesting for the Tier in which the boss will be unlocked, the goal being that if Blizzard releases the 3rd boss is that his loot will be interesting compared to what you can loot in PvE.
Ordeal
The Crucible will be updated to Warlords of Draenor and Blizzard also wants to extend the functionality. It will also serve as prerequisites for raids. Players will, for example, to get into a dungeon queue, have at least a silver medal in the Crucible. If you want to make an instance with your friends or your guild, do not worry, you'll be free to do so. But for a random group, you must prove that you are able to manage certain game mechanics and abilities. This will be ready for the launch of Warlords of Draenor. Blizzard believes that this will make the overall experience better players LFD or LFR. Every player has and the minimum knowledge required to face the boss.
Boost at 90
The boost at L90 operate differently if you already have a personal high level or not. If this is your first character and you go directly to the L90, the game will ask you to use first few three or four skills to familiarize yourself with the game, then you will more gradually. You unlock your skills gradually. A Mage could for example start with Lightning Frost Nova and Polymorph.
This is true for Warlords of Draenor. However, the boost to the L90 will be possible before the release of the expansion. Blizzard is aware of the problem but believes that at present, those who benefit from the boost will mainly players who already have one or more characters and therefore already familiar WoW. It is a system boundary: Blizzard wants players benefit from this feature as soon as possible, but at the same time recognizes that there is a danger that characters mismanaged by lack of knowledge of the players.
Zone PvP Ashran
PvP Ashran area draws a portion of its source in Alterac Valley, at the time this battle could last 30 or 40 hours before seeing a winner. You can go in the area for other things PvP. For example you can retrieve resources for your faction. However, the opposing faction will also do, which naturally cause the PvP area. These materials will help you various things, including the invocation of creatures like Alterac Valley.
Garrosh Hellscream
If Garrosh will be present in the extension, it is unlikely that the face again. There are many other enemies to fight and die rather than go back again on Garrosh players have already fought.
