Recently I found out about a browser based raid simulator used to practice fights outside of FF14. What a awsome concept! Ive been teaching raid fights to people for years in this wonderful adventure and I gotta say this could be a powerful tool if FF14 developed it themselves in a more official capacity.
For years now if my team hit a hard part of a fight I would take us somewhere, lay down raid markers and do dry runs of the particuliar mechanic using me calling out fight mechanics and our imaginations?! This helps a ton and saves alot of time if you have a couple people in your group who cant mentally visualize clearing a mechanic. Often times a hard mechanic is put several minutes into a fight and getting there can be hard enough let alone execute the new mechanic with percision.
FF14 should really look into this as a danger room style option where we can help teach people to overcome hard mechanics in raid at a more classroom pace. Ive been teaching people like this for years just without the fancy tools to act as better visual aids. This could really open the door to new players to gain the confidence and skills needed to do more complicated raids.
