So here it is.
It has been more than 2 months since i started the D3, and i can say that things are indeed changing while you play, but there are not that many as you might expect, i even can say that are a little bit less than expected by any of the players. Some changes that indeed made significant frustrations or smiles come, again, from updates/patches which on my side only made me mad. For instance the overall items attack speed reduction to 1/3 was a huge thing, since before it, i bought (for more than 200k gold) few items in order to have more fun, and then this change came and ruined all, i had to change the entire "build" so i can play further. Not cool at all, strike #1.
With the monk hero that i was playing in my article before, i reached to level 53, just last night, i am in act 1, hell difficulty, and things seems to be a little bit more easy then in nightmare; this could sound crazy but, now since the auction house is a small paradise can provide with cool useful items that will win the game for you, instead of having some strategy of attacking any group of foes or even in wha tit comes to do the campaign/story. Not cool again, strike #2.
I also started other classes, and the one that impressed me the most is the witch doctor, which btw rocks! I consider it the most dangerous when it comes to normal attacks and group control (which represents 3/4 of any gameplay that i do, the other 1/4 is running away :) ). I found an item, a dagger, that had +19% attack speed, which, along few other itesm, raised the overall attack speed to a +33%, in this case the game is so darn easy, i jus tuse normal attacks on the enemy, from far away, doing the most damage. If by luck i do find a blessing for attack speed that means it will go to +58%, where any boss cant do anything against me, i am to darn fast :) .
A big dissapoint is the daemon hunter, she cant do too much damage in nightmare difficulty, she cant actually do anything except runnning away. This one would be strike #3.
Overall, the hero classes are not ballanced at all, the PvP will definetly add more changes to the heroes, this is why i am trying to grow my "army" as much as i can, who knows what stupid changes will come next.
Have fun.
