Completely unacceptable Unity 5 upgrade

There is something basic in the Roadmap of any Application.
We, as professional developer studio, can not accept what is happening to us.
This is the third time in 5 months we tried to move to Unity 5 and we have to come back to Unity 4.
First time we tried on Unity 5.1, and there was an important lag in terms of FPS when using Android.
Second time we tried on Unity 5.2.1. That time, things goes well, and we prepare all our games to move on. When we were most already to do the migration, 5.2.4 was available. So we tried to do it, and we experienced a lot of issues with Unity Ads. We developed our own system to share Ads from several AdNetworks, so for us is mandatory to initialize the UnityAds system on demand and passing as parameter our game, so we are not happy having to set and link the game directly thru Unity Services/Ads.
So we suffered the issue of having added Unity Ads two times, one for the Built-in engine, and the other one added from the AssetStore.
So we back to Unity 4.6.9 again.
Last days with the release 5.3.1 we tried again.
This time the UnityAds issue was resolved and we didn't experience any issue using our own system, and there was no issue sharing AssetStore plugin and the built-in one.
But this time we experienced again a FPS drop in our Android games.

So as a result, after many months of Unity 5.X released, still there is no any version where you can smoothly upgrade from Unity 4.
And also and the most important, is Unity 4.7.0, released some days ago, will be the latest release, because the release 4.7.0 will be discontinued on end of December.

So it looks it is mandatory to move on Unity 5, but Unity 5 is far from the performance of Unity 4, at least for Android games.

So why?

We're paying the licenses, and they're not cheap prices. Several licenses, even the Android addons, and we're in a very difficult position, where most of the assets in the assetstore were moved to Unity 5, and we can not jump to Unity 5 because of this incredible fail and constant regressions.

Our next try will be in March, when Unity 5.4 will be released, with the hope the latest 5.3.X release will be tested and ok.

Really, do you consider, your Unity 5 release is a good release today to do an smooth upgrade from Unity 4 and at least get the same performance in Android games?

Completely unacceptable, and completely unexpected from Unity.

Best regards and Merry Christmas.

 

Did you try to exclude OpenGL ES 3?

 

Yes. It is excluded, in fact is only OpenGL ES 2 added in the buildsettings player.

Thank you.
