Before revision:  The method has become a state-of-the-art technique for combinatorial games, however, in more complex games (e.g. games with high branching factor or real-time ones), as well as in various practical domains (e.g. transportation, scheduling or security)  efficient MCTS application often requires either its problem-dependent modification or its integration with other techniques.
