Due to the fast-paced nature of Blizzard’s Diablo franchise, gamers usually have no problems completing the game in a very short period of time. However the thing about Diablo is not so much the story itself, but its items which are randomly-generated meaning that you’ll always find a piece of armor that could potentially be better.
That being said if you’re getting a bit tired of the grind, you might be interested to learn that Blizzard has recently released a preview for the new set items that they will be introducing to Diablo 3 in Patch 2.3.0. For those unfamiliar with set items, basically these items when worn together will introduce bonus stats or passive abilities/spells.
They also produce a uniformed look which might be of interest to Diablo 3 players looking to collect set pieces. Patch 2.3.0 apart from adding new set items will also introduce new and updated legendary items, along with seasonal legendary items for players participating in Season 4.
Unfortunately Blizzard did not mention when Patch 2.3.0 will be released, but it is being tested right now on the Public Test Realm, so if you are curious about what you can expect, you can create a character on the PTR to find out for yourself.
