Too many balance changes in this year

It’s from ashes of outland that we see more then 2 balance changes, nerf or buff as you wish.
Perhaps it’s from descend of dragons when we saw 2 patches for galakrond shaman.
In this new year 5 balance changes for each expansion, it isn’t too much?
4 patches only for demon hunter… 1 for the problem of mana cheating on card that now are unplayable, i’m speaking in particular of galakrond in rogue and dragonqueen alexstraza.
I mean the meta, both wild then standard, need to settle down.
Wouldn’t be better to do less change, at least less patches with a lot of balance not 2 or 3 so we would have time to understand the meta and find out new deck.
Now we see a patch each week or 2. How it’s even possible?
