*please note that this is a Beta and not the final product.
This phrase is best applicable to any alpha or early beta versions where things can change quite wildly.
what is a Beta for then? i should rephrase my post;
*Alpha the new Beta
what they should do is put it in bold writing on the game screen while people are playing, they say it time and time again, yet here we are where someone is saying "should i by the game?" and everyone else says "No not based on the Beta"
At the same time though i understand what you are saying, i think people underestimate what Diablo 3 is, it's actually got a far more complex items and skill system than in the past and trying to make the entire game balanced has been a nightmare. Personally what i have seen during the PTR and Xbox version before that(what i have played), the game has improved in all areas, it seems now that they have most things nutted out and the game play is good. However, there are massive issues right now on the PTR that seem more like issues before the last patch where things weren't updated before release, which is table based stuff in the items and skills, i wouldn't consider that major.
Unlike a patch in a live version, smaller teams work on smaller tasks in the Beta where testing isn't done to the same level and the most important issues get the best work done, that makes issues like this possible where things are missed... where on a live system everyone would be working on the tasks and testing to the highest standard. So the issues, might have been amended just not released/updated when it was patched - seems like they are well into the fine tuning phase and someone plugged in the wrong code before the last update or something, that is why you shouldn't base anything off the Beta.
Don't get me wrong, i don't want to start a fight / debate or anything i'm just posting from the positive side, because 3 people decided that it was battlestations time and everyone should be worried, yet there is still 2 months of time to clean things up.
