Every expansion, the devs nerf a few species. Mostly not by a huge amount, but enough to take a bit off the top.
In general, I approve of this effect and this cadence. It makes a small overall change to the most used pets without damaging their integrity.
Until last expansion, I could also say that I approved of the changes. Teroclaw, Undead racial, Haunt and others were appropriate. I still grieve a bit for Howlbomb, and I think there was a better fix for Teroclaw, but mostly they got it close to right.
Until last expansion.
There we had a sorta-kinda nerfish thing for Shattered Defenses that did almost nothing to tame Ikky, plus a totally insane and unjustifiable buff to Sandstorm damage that still has my eyes rolling. While not quite as wrong, I’m still somewhat exercised about the Shattered Defenses mistake, which hardly affected Ikky - which is the actual problem - and damaged so many reliable but not overpowered pets. I demonstrated this on spreadsheets in the Beta forums, but was yelling into the Void.
And then there’s what they did to Flurry. 
A huge disappointment.
What I wish we might see this year is to undo everything they did last time, then make a targeted nerf to Ikky and a couple of very small nerfs to maybe Anomalus, maybe TMD?
But apart from that wishcasting, the question here is what you think they WILL do.
In previous expansions - I think the last three? - we had some advance communication about the expected changes, allowing for some feedback.
This expansion, so far, nothing.
I think we will see no changes this time. I’m not sure they have anyone paying attention to it.
