one cool feature you notice is your tab space seems to have improved, as you venture further into the game you realize the unquestionable amount of rares that drop this is indeed an improvement, you also notice that the main attribute stats seem to accumulate as well, 100 str on an item at level 11... okay lets put it on!
You will spend hours on in fighting through the mechanics of the game only to get to where we are all at, level 60, so whats next? you notice as you grew in-dept with the game there is no more hostile button its been replaced by a NPC that allows you to teleport to a short term map that is hardly worth staying more than 30minutes, and you will soon become disappointed by the amount of skills you through off of your list due to common sense in terms of damage / defensive calculating.
just to break it down for you in a TL:DR Version
as of 4/29/2013 review
# Barbarians Spin to win are the top for Monster Power 10
# Witch Doctors are the best in terms of PvP for the Dot damage and Survivability
# Echoing Fury, Skorn, Calamity are the most strive for items
# There is Duping we wont lie about that both RMAH/AH
# 24/7 Trolling on the forums (mainly upset gamers)
# Untrusted Hardcore players
# An item system so bad it tries to compare its stats to World of Warcraft. (ex: 1.08 Item has 300str, 1.09 350str, 1.10, 410 str, and so forth)
# Unlike Diablo 2, Items lower than ilvl63 wont provide a means of upgrading your character, other than the Stone of Jordon which gives you a max of 30% Elite Damage.
# One of the easiest boss mechanics you could ask for, Changing the modes wont change the way the boss fights only the damage and health increases.
# No In dept Skill Tree or Skill Talent Points, Passives, or Skill Auras for Items that would provide a means of a Different Build.
#Magic Find is not a stat you could rely on at (Paragon 100) with 300% MF including shrine buffs i had to BUY all my stuff in the end
# No more Cow levels, its been replaced by a cartoon series called " My Little Pony's "
# And lastly this game is 100% Anti-Grief mode, other than the abused glitches on Hardcore Mode, your expectations to walk into a game and hostile a whole room of people will not happen.
