Ranked in these QuestionsQuestion Ranking
Pro Fun endgame with even better loot
Once beaten, the game adds an option to play over at a higher skill level, which also allows for better chances at better loot not found in the first run. This makes for much replayability through gameplay that may earn the player newer rewards.
Pro Heavily focused around customization
About 30 activated skills per class, 5 unique runes per activated ability that modify how it behaves, and randomized gear that can further change how your character plays.
Your playstyle might dramatically change based off of how you want to cater to your team, what abilities you might have just unlocked, and whether or not you want your goblins fried or diced.
Pro Really big boost in experience if playing of hard
By playing the game on higher difficulties users get a 75-1600% boost to their experience, which makes for a great reason to deal with hordes of very difficult enemies where one simple mistake ends in death.
Con Less focused around growth than previous installments
Previous Diablo games were known for having permanent improvements throughout the game, where Diablo 3 focuses more on customization as you increase in levels rather than improving your abilities. There's a chance that you will unlock your favorite ability at level 5 (I'm looking at you, Rapid Fire) and never use anything else in the game, because you can. Many people consider this an issue with Diablo 3, and expected more of the "specialist" style of gameplay.
Con Still requires the player to be online even to play single player
Basically this is an always online DRM scheme that forces the user to have a constant connection to the internet in order to play, even when playing single player.
Con Semi-MMO competitive nature
With the introduction on seasons, people play it exactky like D2 ladders: 24/7, botting, account sharing to keep at pace in leaderboards. Not feasible for completionist, players.
Con Endless experience/grift grind
It's an eternal buff/nerf game, with torment levels to increase with paragon levels and grift number.
