I think Coil's difficulty definately increased the longevity of the content. I guess it's cool that Alexander is more accessable, but i think they went way too far. Now the entire raid can be beaten in a day... which means after a few weeks, you probably already beat the bosses like 10-20 times and it's not that fun anymore. We barely halfway into 3.2 and I don't even do Alexander anymore, and the next raid tier doesn't come out till 3.4 lol.

They prob should have made normal mode more like coil with echo, then slowly made it easier over time for people that are potentially stuck on it.
