This.
The Necromancer I had just used the random Dark Brotherhood Assassins that always show up to the Sanctuary after you finish their quest line. These guys come with some of the better skill sets as far as NPC's go (IMHO), and thus make great Dead Thralls.
But like Llama said. Adapt. If you are really in the minority as you claim, then why would they change a game mechanic that will affect every game that everyone has? Your own argument defeats itself.
Just chill out and rethink how you are doing things. Even with the 1 day window, I'm sure that you could still tweak your design so that you can still keep your play style.
Well, if the game had been made this way from the beginning, you might have a point. Hell, I wouldn't have even registered this complaint if that was the case; I would have been bummed about it for a few days like so many other things I loved about Oblivion that either got omitted (spellmaking) or butchered (move-drag feature), but I would've moved on an accepted the game for what it is. However, sliding a change like this into the game under the vague pretenses of a patch isn't even in the same ballpark as releasing it that way initially.
And if this was something that equally affected both the majority and the minority, I wouldn't complain then either. But this is a change of very minor import to the majority and very severe import to the minority - I highly doubt you would've even noticed this issue, let alone the microsecond that the 'fix' saved you in load-screens, had I not brought it up. As I've said before, since I've been playing their games, they've never gone after corpse-refresh rates as a way of reducing lag / bloating, so this certainly isn't common practice for them.
As for 'adapting' to the 1-day refresh window, that's a pretty cheap excuse; your definition of 'adapt' is 'deal with the bad hand you've been dealt halfway through the game and like it.' There is no wiggle-room for the necromantic RP style as it was prior to this patch if it takes you over an in-game day to travel from Markarth to Riften, other than to cling to the precious few perma-corpses who are actually useful. I've spent the majority of my thousands of hours playing Bethesda games learning to 'adapt' to things within the framework of the game to play how I want (and subsequently passing that knowledge onto others), and for you to suggest that I should just continue to just blindly do so rather than for you to actually consider just how little you'd be giving up to put things back to the way they were is pretty asinine, honestly.
And you might be thinking to yourself right now 'well why don't you just quit *****ing and delete the patch?' That's sound advice that I've already followed up upon, save for one key thing: unless Beth has radically changed their programming methods, you can't play the DLC without the patch. So unless this change gets reversed back to the original state, I have to choose between playing the game the way I immensely enjoy it or playing the extra 50% of the game, which is a bummer either way it's sliced.
