Auto corpse recovery makes a lot of ubers not only easier - but completely removes their difficulty. You can now put a "difficulty: 0" at most of the CMxl ubers with this system.
I will provide an example: I have leveled a melee axe barb to 120 in sp, my gear is pretty bad although I have 1,5 million def (maxed bear stance + runes in all items ofc). I did some of the really easy ubers: king koth, tal rasha, creature of flame, death projector, infernal machine, iotss (which admittedly is fucking cancer for barb because of Malic) and then I decided, since we have auto corpse recovery why not head straight for the cathedral of vanity? Well, I entered it, didn't care about anything at all, didn't use my brain, just tried to do as much damage to the spire before I die. I died, took corpse back and repeated same thing for 5 times, then spire died and I killed everything else. I concluded that this uber is not tricky or easy or whatever, but literally trivial, 0 difficulty, you just need a bit of time to do it, no need for brain or anything, which is sad. In previous patches, if I was not able to do this uber I'd try a different approach or come back when I'm a bit more geared, and when I, especially when I was a new player, finished the uber, I'd feel very satisfied. Now I don't. Because I cheesed it.
With that being said, does my post actually have any significance, does what I said actually matter, is auto corpse recovery a problem? no. Why? Because like someone above me said, when Marco took over, this game became more MP oriented, and due to that (and also because we have a stable and "official" server) most of the players now play MP, and in MP they can of course rejoin games like they always could, so the only thing corpse recovery does is make the MP corpse recovery less time consuming and removes the disadvantage SP players had compared to MP players.
So in short, corpse recovery:
>MP corpse recover (rejoin) is now less time consuming, SP players are no longer at a disadvantage.
>removes a lot of frustration from the game
>is overall a very good thing
People who complain about corpse recovery are complaining about a part of the problem and not about the root of the problem. If you remove corpse recovery, you make the game more balanced for SP players (because the first ubers are no longer trivial) but you also put them at a disadvantage which is very unfair, so it would be silly to remove it, besides you would just make MP players more frustrated.
If you wish to get rid of corpse recovery you must also get rid of being able to rejoin games. However, recovering corpse was really hemorrhoids, so I tihnk auto corpse recovery should stay as is. Removing TPs is not a solution at all and the only thing it will do is add a huge amount of hemorrhoids.
The real problem here is being able to throw your body onto an uberboss until it dies, without needing ANY gear, skill or brain to kill that boss. Of course Marco said there will be timers and events where you can't recover corpse etc but from what I understand, "events" or what marco had planned are completely new, so is it not planned to adjust ubers like CoV with some mechanic to prevent throwing your body at spire until it dies? I understand CoV is now one of the easier ubers compared to the new ones, but it's overall not THAT easy and reducing its difficulty to completely 0 whether it's with auto recovery or Mp rejoins is a bad idea imo.
I thnik I wrote too long of a post for something that could be said in a few words. My point is:
Corpse recovery is GOOD, but something must be done to prevent cheese with corpse recovery AND MP rejoin, and such a prevention must be applied to ALL ubers whether it's some really hard or really easy one, because even the easiest uber has some base difficulty, however at the same time you must consider that there are ubers that are pretty much only possible if you die (if you're playing certain builds). For example I've heard multiple times that uldyssian's baal is doable as a melee sorc only if you attack him until you die then take your corpse and repeat same thing over and over again, and the real fight is against baal's hp regen and not himself. So if you make it impossible to kill uldy's baal by throwing body at him you must implement some alternative way to be able to do him as melee sorc for example.
