1. Exotics for the cheap price of karma and can be acquired by your main for your alts. When you can get Ascended gear for karma or some other cheap method instead of a long-ass grind, let me know.
2. These are stat combinations previously unavailable in exotic form other than those rare-ass dungeon recipes (if that). Nothing shameful to say about the addition of more variety to the gear.
For example, I'm still rocking PVT rares (yellows) for some of my jewelery slots because anything in exotic/ascended form was previously unavailable, too expensive, and/or grindy to get.
3. Ascended accessories don't exist yet. Only backpieces, rings, and amulets. Therefore, exotics are still top-tier for accessories, of which these are.
