Rule change proposal for scorless draw matches in JLeague

Traditional league points scoring grants 3 for a win, 1 for a draw, and 0 for a loss. The new rule would be that a PK shootout is conducted after two 45 minutes halves without goals (0-0) for all league matches including group leagues, such as the group leagues in WorldCup/Champions league. In the new rule, PK winner receives 1 point and a loser receives 0 points. All the other tie scores (1-1, 2-2, 3-3, etc) do not have PK shootout and 1 point is granted, which is the same as the old rule. This new rule doesn’t apply to tournaments, playoffs, home & away knock out stages. A lot of soccer fans complain about scoreless draw results in soccer matches. Not every match with a scoreless draw is bad but adding PK shootout will make soccer more exciting to watch. Especially giving 0 points to PK losers will make each soccer team in a league play more offensive and more eager to score in their matches. By adding PK shootouts, the scoreless matches are no longer a disappointment for soccer fans. I strongly believe this new rule will be a huge reward for soccer fans. Please comment if you see any drawbacks in this suggested rule. Any comments will be greatly appreciated.
