PvP is restricted to as PvP, you are unable to force anyone into PvP. This is a feature that does not equal the TES IP, but represents the current business model favored in MMORPG's. Not to mention this eliminates the possibility of being assaulted by a PC member of the Dark Brotherhood / Moraq Tong, a feature many TES fans would have endorsed. If PvP is out of the question, so is thievery, and thus, even thieves guild will be null when in regards of PC characters.
3 way faction is a feature of DAOC, along with RvRvR being hidden behind "FvFvF", and a lot of these factions make no real sense lore-wise.
The gameplay (combatwise) is to represent a traditional MMO with "something new" versus the "first-person-sworder" that exists in TES games.
Now, this is complete bull and excuse. If you'd tell this to the engineers behind SOE's new MMO engine "Forge Light". They would laugh at your face. Currently Forge Light is used in an FPS game called "Planetside 2". Which currently supports hundreds of players simultaneously, whilst has real projectile physics (no hitscans), it has seperate hitboxes for all characters / vehicles. Forge Light will be used for Everquest 3, and we are yet to see how this " PvP focused" version of EQ will turn out, perhaps we'll see something TES:O combat should be about, a continuance to the series. P.S Turn-based fundamentals are not part of critical design, they are design barriers that used to exist thanks to the technology not allowing to perform better.
Traditional MMORPG designs instead of favoring the TES IP, again. In TES, you could level up with non-combat professions, such as speech craft, theft, crafting (Alchemy / enchanting etc), or just purely skills such as acrobatics and athletics. Now, you are supposed to do the traditional MMORPG "grind" to level up.
The interesting part about PvE is the fact that it features a storyline, which however sounds rather boring in comparison to other TES versions. Your soul has been stolen, really? Also how will it function that everyone in the game will be the hero, it can be argued that it will destroy the immersion.
I could go on forever, but I believe these will cover the keypoints.
TL;DR The game should be a sequel to TES franchise, instead of being a DAOC endorsed by DAOC fans and traditional MMORPG players, whilst pissing off the entire TES fanbase.
