Yeah but if you look at the time it takes to gear a character for effective raiding... you can easily gear multiple characters up to do so. It doesn't take a perfect set of weeks worth of gear to do 99% of the content. All of our hardcore raiders can play multiple classes for raiding content Thor Ex etc. Time tapers it some yes. But its not a permanent locked out state.
I "think" have been ok if they had gone with a tapered design like that for crafting, where you could only viably gear up one character fully and the others less so, and then start working on the next and so forth. I THOUGHT red scripting was going to be like that. But they completely fubared that up, turning it into not just a time investment but an absolutely insane material investment. Then after that failure they jumped to locking recipes out.
It all just shows me how uncreative and hopeless they are at this point with their crafting system. Suffice to say they are doing a great job at sucking the fun out of it.
