Guild Wars 2: HP Train Tips and Setup

UPDATE: Learned that the colors of tags that I use are not colorblind friendly. The best ones to use are white, then yellow, then either teal or pink but teal being the best choice of the two. Ignore that part of the video if you'd like to be mindful of colorblind folks. :)

Hello all Aixxel here with a video guide on how to get starting running HP Trains! In this video I discuss how to get a Comm Tag and what the Comm Tags lets you do. How I setup my HP Train and some tips with it as well. I apologize for the video being super long but I wanted to be as informative and as helpful as possible.
