How attached are you to your D2 characters that are only a delete key from being erased. Make a mistake in spending points and presto character is deleted. Now players that want to make alts can do just that.
That just doesn't add up.
I say that the best way to have the majority of your characters where you can truly say that they have all self found gear is to work hard on one character and get that one's paragon level up good enough for the purposes of making him/her a farming character. Then the rest of your characters can be for fun. Just to kick around with, trying out extra builds. Going back through the leveling process just to see a build develop. You might even want to try out the lower level content with a new character when the game makes major changes to the lower levels of the game.
In WoW you would have players that would have alts for various purposes. On would be for raiding, another a bank alt, another a mule alt, another an auction house alt, etc... So why not do something similar here.
2. Balancing the classes is something that will take a while to achieve. Anyone should know that, there is no magic wand that they can wave where it will instantly balance the classes. That sir is just impossible to accomplish. the problem with this is that they are COMPLETELY un-balanced. you have monks dont even have the same NUMBER of passives as the others do. forget about what they are, simply less choices, regaurdless of what the choices are.
3. They are no doubt working on making more endgame content. What it will be is unknown for the moment.like to assume do we? and you got one thing right, it will be unknown, probably even by them.. lol.
Blizz is the type of company that is never happy with their games. They keep making iterations (changes) to make them better. They also said that they are in this game for the long haul. Which means that they will be adding more content in as well. I say that they have to. They know this game needs more content. The dueling will help some, but it will not be enough. Hellfire, Paragon levels, and the high end recipes that are being added in the next patch will still not be enough.
That is logic and that is one of my strong points. I can tell when logic dictates a certain course of action. I just am not sure exactly what direction that the devs will take.
