Valve announces Dota Plus, a monthly subscription feature

Valve has announced the launch of Dota Plus. This is a premium monthly subscription feature within the game itself. It will provide detailed statistics, free cosmetic items, terrains as well as hero challenges. The Dota Plus is considered to be an upgrade to the Major Battle Pass system which was a runaway success.

Dota Plus also features Plus Assistant, which is an AI-powered assistant. Plus Assistant will help you in deciding which abilities to level up and what items to buy. This suggestion is based on the lanes, heroes, and situation of the particular match. Since it is an AI it will take time to get its suggestions finetuned according to the player and the current meta.
