I remember that SE said 1.0 event items wouldn't be available in 2.x. Then they were, and 1.0 players were outraged.

I personally feel if you didn't participate in the event, you miss out entirely. Nothing in the cash shop; you do the event and get the item, or don't do it and get nothing. As an aside, I have one character from the 2.0 beta, one from just around the time of last year's Hatching Tide (2014) event and a new one. I'm not upset about not having the items I missed on all my characters, even though some would work well for their glamours.

Right now, the only things you can't get from previous events at all are the titles; and some of them are pretty good. I get asked where to get Golemancer all the time...
