One of the reasons I chose to play this game is based on an idea that this game does not allow mods or third party programs, but, from what I am reading and hearing, damage meters, parsers, and even screen overlays are widely used by most players in the end game without penalty.

So, in order to play in the end game, I am forced to play cookie cutter because these illegitimate programs are tracking my every move and exposing me for not being completely min-maxed to other players. On one of the promotional pages for these third party programs, a part of the pitch for the program is 'on screen indications to check if teammates are using skills in the right order and on time so you can tell if they are pro or not at a glance'.

This is very discouraging information for me as a new player who bought this game because the main rules page bans mods and third party programs from being used.
