I do feel the same way. The more heroic bosses we kill before they get % nerf the better, but if we don't see the end boss(es) of a heroic tier I won't cry about it. I am just happy that we got to see some of the heroic fights.
Most probably could see more and possible have completed the heroic tier already, if I would be in a different guild, but I value the company I am with more then anything else.
