Well in the long run the terms of service dictates: You may not develop, share, or use any software, program, macro, or interface that modifies the game play in any way or that gives a user any kind of advantage over other end users, except as expressly authorized by Daybreak. All forms and methods of cheating, including hacks, bots, aimbots, and duping are expressly forbidden. So this even means DPS meters like ACT are illegal. That being said it reads from a log file that they wrote for us to touch. But that being said unless Daybreak says it's fine to read from their log file even it's illegal at this moment.
