Broot tree pet

I’ve been collecting my class hall plots for six months now, on wowhead it says the droprate is 40% but that pet still eludes me, did they changed anything or is it just my extremely bad luck? Anyone else got that pet lately?

I got mine late last year if I remember correctly. That drop rate is wrong, no way its 40% based on how many times I had clear my plots. Though it was probably weeks not months.
