Rule number one in these forums: don't take complaints seriously... They may be genuine, but they are just 99% whining. Like the one you quoted, who claimed he wanted to quit playing the game entirely because of some NPC isn't strong.
And then there's the inevitable troll-post labeling a legitimate complaint regarding design as "whining," just like clockwork.
I guess if you're a really devoted fan, you can continue to love a game just 'cause, but the rest of us have a bit of a problem investing time and effort in a game when the confidence they have in the developers reaches a critical threshold. That follower-NPCs, especially housecarls, do not level while adventuring -- but your enemies can -- is antithetical to game logic and appears to be either a painfully stupid decision of the sort usually reserved for politicians or a bug/logic-problem they just decided to ignore. I'm familiar with shoddy product refinement from Bethesda (it wasn't until the UNofficial patches that I got Oblivion to work well enough to play through w/o console workarounds -- yes, that long) but this is a basic design element.
So the question "Do I want to keep playing this or put it on the shelf for a year or three until someone fixes Bethy's plethora of bad decisions?" comes to mind.
So sorry to have upset you, Pistolero.
