Next update - WOTLK, fo shizzl. Just look at CATA realms, how many ppl online you see? 2k TOPS avg = 1k. People are Clearly not interested in playing CATA, why bothering scripting it than? Face it, people want VANILLA, TBC, WOTLK.
Now, look inside CATA realms again, and check global chat... All you can see there is - RHOT DS BH Noone even bothers to go Firelands and Blackwing Descent + The Bastion of Twilight are just some Elder combinations of words that are prohibited to use because they cause massive convulsions.
Go deeper and you can witness how pvp looks like when its 100+ years old, disabled and has constant diarrhea, needs viagra to get a boner in addition to its gonorrhea.
It's just dead ppl. poke it with a stick.... Well.. untill they make some advertisement and make ppl come back to cata, with something free giveaway for coming back or new marketplace items or anything else. And prolly THAN we will see some FIXES.
