Pros
Pro Tons of unlockables to keep you playing
Each playable character in the game can have more than 90 different unlocks such character skins, color schemes, emotes, and victory poses. While these don't affect gameplay, they allow you to create a personalized character you can feel more attached to. This gives additional goals for both regular players and completionists, keeping the game interesting for a long time.
Cons
Con No content creation tools
You can't create custom maps or game modes, which considerably limits how much the community can contribute for keeping the game fresh and exciting. This is a step back when you look at the Warcraft 3 map editor, which helped the game stay popular a decade after its release even without regular updates from Blizzard.
