OP: I played in Vanilla and TBC and it wasn't that hard tbh. I came to WoW because it really was a casual game compared to the game I was played before WoW, which was Lineage 2.
The problem with this game is 99% of your power comes from gear, and players want to be as powerful as they can in an RPG. Even if you don't raid, you want to be powerful. If really powerful gear was only available to those who raided, this game would probably be half as populated as it is now. A vast majority of wow players don't raid. (I don't include LFR as raiding).
So the developers have to put the gear out there. The thing I would really be interested in is the age of those who use the term "welfare epics" or "free loot" etc. to describe the easy way one can pretty much get to 930ish ilvl without raiding. I played in Vanilla and was in the #1 alliance raid guild for my server. I took a 4 year break from TBC to Cata skipping WoTLK. Since gear gets outdated so fast in this game, you really have to have a system in place that keeps players subbed and that means feeding them gear. Not the best gear, but still gear.
I wonder if only mythic raid gear were purple if that would make the 1% happy? Honestly, I don't care anymore what the 1% thinks. This game will be better once they leave and the raid or die mentality leaves with them.
