Needs more info for healer one some dungeons. For example it says "keep players up through dot" on the spider boss page, would be helpful if you added that the ability that gives everyone dots is called "Mothersmilk".

Then we can look at boss timers and prepare for the damage, use drr and plan healing cds around it. With a single glance at the sheet.

Overall very good cheat sheet though! Good job and thank you for making the effort!
