Well, the publishers marketing department has been the downfall of more than a few games. The marketing department is separate from the development team and their only job is to sell sell sell. Facts of the matter be damned. Hyped trailers, fake screenshots, whatever it takes really.
DA:I wasn't made in haste, it was finished in haste. This is a problem throughout the mainstream industry. Once the publisher deadline starts to loom the developers are forced into crunch time to try and finish as much of what they planned as possible before they have to ship. This is what leads to these problems and oversights. I mean there's no way no one at Bioware thought of a storage chest for example. But when told they have x days to finish the game before it goes gold the storage chest is the bottom of the priority list after major gameplay features.
EA has a notorious and checked past with crunch time and working employees to death to get products out the door by a set date ( always set by someone higher up ). It wasn't that long ago they had to settle a class action lawsuit by their employees over unpaid overtime wages, 85 hour work weeks, etc. 85 hours! Without overtime pay. They were basically a sweatshop. There's a reason EA was voted the worst company in America. Labour issues, deceptive business practices, buying out and closing down beloved developers, etc. EA is straight up pushing gamers buttons to see exactly where the line is. The point where they snap and stop paying money.
As for your boss, I'm guessing you don't work for a large corporation and/or you do not work in, around or with American companies where this type of corporate culture is commonplace.
I'm not saying the Elder Scrolls doesn't have good lore, it does ( even if it has a hard time keeping it straight ) I'm saying that DA's lore is hardly McDonalds compared to it. The Elder Scrolls has always been strong on lore but weak on writing. You don't play Elder Scrolls games for the story. You play them for the freedom of the sandbox world they give you. Dragon Age is the other way around. Neither one is better honestly. They're just different flavours.
Kingdoms of Amalur on the other hand is as generic as they come. It was pretty much single player WoW. Even the zones were analogous to zones in WoW. Never mind the art style. Filled mostly with generic MMO style quests to fill up all that space. The combat was decent enough but the game was poorly balanced. It had the same problem as practically every Elder Scrolls game: You could craft your way to absolute godhood. Then there was the class balance where mages ruled all. It was a fun enough distraction but like you I was basically just playing it for lack of any good RPGs to play at the time.
Sadly we don't get really good rpgs that often and half the games that get labeled as RPGs are just action games with some stats thrown on top.
