I like the random drops. Yeah its based on luck but you need to look at the games life span. Everyone would quit if they just geared and got world best stuff. With this system you are rewarded the more you play. Yeah, You can hit a gold site or buy items from the RMAH but enjoy paying 250$ per item or 100's of dollers in gold just to make yourself decent.
The only thing that "RNG itemization drops" does is make sure there is no true BiS item. Any drop you find can be that big ticket item. I know this because back in the day i got back to back ring drops in Act2 that ended up selling for 317m and 550m. Its luck. I've found around 8 items thats sold for 2 billion and i have even made some cash in life selling gold so i think the game is perfect where its at.
People are being way to harsh, Wacthing what people say about the game makes me think " Man these guys need to take a good look at diablo 2" and when they say : Oh i played D2 for years! I just think "Yeah right" D2's got nothing. All the D2 vets i play with agree.
