The bottom line is this do you have the authority to access another player DPS Logs without there consent by means of third party software? The answer is no, if you were permitted to do that then that system would be made public in a game and it is not. Now if the information was only seen by you then yes that would be a great resource. The fact that every player in the data center can see your runs of ever dungeon along with your DPS ration without there consent is illegal. Now lawfully this may be acceptable but in terms of the TOS, you are not permitted to do it without the player concent. This is because this information can be used to harm another player and that is against the term of service. Therefore I will be forced to report this website to SE so it is taken down.
