I always do the full pull, most can handle it. As someone else mentioned, wall to wall in that dungeon was possible during early access, and was only really hard if your healer was an AST. I had a WHM pre-savage heal the full pull with all level 79 gear, so there really isn't a good excuse at this point but to try it. If we do wipe, the healer likely wasn't ready for it (when I leveled my SCH to 80 by grinding dungeons it was rare for a tank to pull big) they likely haven't had practice using their full kit (since dungeons are pretty easy to heal 1 group at a time). The community will grow as a whole of we push each other to play better and work harder.
