Got a long break so I’ll write this up. Hope it helps.
ENDGAME.
GD revolves around build diversity rather than never-ending grind to improve your favorite character. Most advanced players have the number of fully leveled characters in 2 digits. This is probably the most characteristic feature of GD.
MP.
In GD MP is a feature rather then the soul of the game. PvE is fun and especially good for beginners who struggle with the content and farming. Trading community is quite vibrant and with just a little effort readind ads and talking to people you can easily acquire any item is the game except very rare greens with specific affixes and purple MIs with very low drop chance.
LOOT AND GRIND.
GD features a total RNG loot system with a relatively large number of affixes meaning that, outside certain items, it’s not very “specific”. There are two tiers of affixes: magic (yellow) and rare (green). And then there are two tiers of unique items where stats are constant (no affixes): epic (blue) and legendary (purple). The range of rolls on stats is quite wide.
Almost every beginner complains about the loot. The proportions between yellow and green affixes and then between regular and unique loot are quite prohibitive for beginning players. But once you are able to efficiently farm, those complaints you made in the past begin to seem infantile. Besides, trading community helps a lot with gearing. Strictly self-found game is considered to be somewhat hardcore at the beginning stages.
However, GD is free from the plague of microtransactions meaning the developers don’t feel compelled to artificially restrict loot in order to encourage players to spend more money. I say that it is for this very reason that GD wins against its aRPG competition when it comes to loot.
Crafting and component farming has been greatly improved since the first versions of the game. You do have to farm for certain components but it does not feel like a chore. Especially once you expand your inventory and actively trade with beginners - then there is hardly any need to farm anymore.
As for EXP, this is never a grind. You can comfortably reach max lvl just by following the story. Leveling devotion EXP when you change your setup late in the game might require some grinding but it’s not something many people complain about.
BALANCE.
Environment in GD is very well balanced to provide sufficient level of challenge for beginners. However, many advanced players complain about main game being too easy.
There are no buggy enemies that make you pull your hair. Once you have mastered the game mechanics no enemies pose much of a threat for most builds. There is an exception of optional Celestial superbosses who usually require some preparation but regular bosses and nemeses (faction bosses) are conquerable by any well made build as long as you know what you’re doing. In GD when you die it’s 100% your fault.
GD fails, however, when it comes to the balance between different classes and builds. Some classes, concepts and even damage types are visibly superior to others. But it’s not a PvP game with so imo it’s not such a big deal.
