Please improve the combination of pets in the game, I spent a lot of real money buying the best pets, and since each active ability of all the pets does not add up, I decided to combine them to improve them and I keep getting much weaker pets with this will lose all my savings and expenses, really the whole gatcha system is quite unfair, but gatcha within gatcha is a lot, some of us don’t have all the money in the world and we strive to put money into the game to have some improvement, and Even so, with the new pet system, its randomness is already too much. Not to mention that to improve a legendary gem (which already costs a lot to get) to level 4, you need to get more than 8 of those same gems, but the old players DO NOT HAVE all the retroactive telluric stone time. It is really understood that you win more in the game like this, but those of us who place money also hope to have that “luck” that some seem to have at first
Yes, I strongly agree with you on this. Though in my case, I had 3 yellow pets with great attributes and traits, hoping that they would produce a better when combined thru “convert”. But to my surprise, it resulted to a blue pet with trash attributes / traits which when I sold in the market, amounted only to 4,000 plats. 
this is so frustrating.
I can agree with this. For every layer of consecutive gacha the odds of inprovement should also increase.
Like with Phantom Market mechanics. The odds are initially set with the first free draw. Each draw after that increases the odds of getting the remaining gacha
If you “spent a lot of money” you are automatically wrong, because Blizzard doesn’t need you anymore. Except for getting even more money from you, so they might consider your opinion.
Welcome to the world of blizzard. What U think why it has been designed like this? to get a nice leg pet for few bucks?? 30% to get aberrant during regular conversion, without any guarantee you will have a good one (and 90% of the time the converted will be a piece of crap, even if U used 3 good pets). Solution? Buy Darkling vessels from shop and summon more and more and more. there is exactly 5.78% chance to get a rare aberrant familiar, and from that 5% only 28% to get 1 leg skills, 8% to get 2 leg skills. Basically U have 0.5% chance to summon an aberrant familiar with 2 (not 3 -5 ) leg skills.
Yes this is a MAJOR problem.
LOGIC 101 - 3x equal pets, being either 3x blue, or 3x grey, or 3x yellow when combined should at the very WORST, do nothing., NOT depreciate. THAT is a RIPOFF. The thing is for some reason BLIZZARD/NetEASE thinks everyone will keep tolerating this. They forget that the richer people who spend a lot of money did not get rich by giving their money away.
The INCREDULOUS - I have one pet being the lowest which will remain there forever. WHY?
I converted 3x blues together. They produced technically a pet of much lower quality and less skills in damage, but gave it the salvage trait. It will remain forever untouched now down the bottom. That is all wrong.
EDIT - Read up on the whales on Reddit and Diablo Fans who are complaining about their familiar losses on conversion. To say they are annoyed is an understatement.
