Make them BTA.
Making them BTA would help with gearing of new alts. Some of the Eberron epic items take a lot of work to create and are now useless on the toons that have them, rather than ask for a buff to those items I'm just asking for the BTC flag to be changes to BTA, like what happened with the epic wands.
This way I can keep moving my old epic items that were great before down to new alts, who would actually get some use out of them.
Epic raid items can stay BTC for the most part, that's fine with me. But Chronoscope stuff should probably go BTA, as they're BTA on non epic.
This is not meant as a catch all solution for people with a backpack or 5 full of purple shinies, but just something I thought would be easy to implement and would at least give those old items some possible new usage.
