Use of tools that allow players to more easily complete content. Discord?

[sagacious]

I just would like a clarification because according to that statement discord isn't allowed and breaks TOS. 1st time I cleared a savage was after ten tries I got on a team that used discord. The leader was well spoken and told us where to go and when. I cleared that savage easily all because of him. It is a tool that helped me complete the savage easily yes? or no? I need a definitive answer to the discord question. Use it yes allowed or no not allowed ...why do I need a definitive answer? because I do not want to get banned or suffer for 10 days
