Please Fix Engineering

So there's some engineering items out there that aren't just a little bugged, they don't work at all the way they're supposed to. It's been a long time since server release, and these bugs still aren't addressed. Will they be fixed anytime soon, or ever?
I just trained engineering recently, only have a few of the trinkets, and I've already noticed the following are severely bugged, for example:
Gnomish Battle Chicken
http://db.vanillagaming.org/?item=10725
If you read the dbvanilla (wowhead) comments, the chicken is supposed to occasionally use an ability called battle squawk, which increases the melee attack speed of your party by 5% for a few minutes, which made it great to use in raids before a boss. You would summon your chicken, try to get the buff, and if you didn't swap it out for a better trinket before the fight started. The buff though is completely missing, which makes this item borderline useless. Also the chicken is supposed to last only 2 minutes, instead it lasts forever or until it is killed, I don't know why.
Gnomish Mind Control Cap
http://db.vanillagaming.org/?item=10726
I don't know if other people have had better luck with this item than me, but I only rarely have been able to get the mind controlled player to attack or do anything besides follow me. The mind controlled player is supposed to act like a pet, you should be able to tell it to attack, stay, follow, aggressive, defensive, passive, etc. And again if you read the comments, it is supposed to use the mind controlled player's abilities as well when you send them in to fight, of the few times I was even able to attack with the other player, they just autoattacked in melee and nothing else.
These are just the two I've encountered. If you know of any more, please mention them. I'm hoping the devs will fix engineering to how it's supposed to be, if we bring some attention to it.
