If you obtained a trinket or a weapon back when, the rest should be unlocked.
Suddenly most powerful heirlooms because SOCKETS!Pity I missed out on the vast majority of them... Just got an Int mace and off-hand ... :(Why'd they even remove the damn things... they're flippin' heirlooms, not mounts!
whas about time...
You could put the xp gem into these weapons and get the benefit from that, and the battlemaster trinkets gave 50% extra xp from bg's.
The Garrosh weapons are also still higher itemlevel. For example, on a level 1, caster, the Grand Staff of Jordan and the Dignified Headmaster's Charge are itemlevel 2 with no stats, while Hellscream's War Staff is itemlevel 4, and has 5 intellect, 2 stamina, 1 crit, and 1 mastery, in addition to the socket (which themselves grant another 2 intellect as a socket bonus once filled).Edit: also, the Legion trinkets are usable at level 1 as well.
What's really frustrating is that I had all of these heirlooms on mythic, I put in a lot of effort to farm them. Then when the transmog changes came around I somehow didn't have the 1h axe in my heirloom list.Made a ticket but was essentially told tough. Now it's the only one I'm missing and they aren't attainable....
