I realize that BETA testing needs to happen. And I am not suggesting it should be ended.
But it does lead to unfair advantages, especially when the information is kept secret allowing a limited number of people advanced information.
Specifically, SG will have some sort of new building to allow players to use heroes to generate a different existing hero. Just knowing that it will take, as an example, in Beta 4 4s to get a different 4 is very useful.
I realize that SG almost always changes the Beta in some way but the beta testers will have an advantage.
Right now I am not burning any 4 or 5 *s since I have no information as to what I need or may need, not to mention what else may be needed for the transformation.
At the very least, for this change, SG needs to publicly discuss what is needed at the start of the beta testing and disclose all changes during the testing. And, once the final requirements are set, publicly announce them a week before it goes live.
AND YES, I WOULD LOVE TO BE A BETA TESTER BUT REALIZE IT IS VERY UNLIKELY TO HAPPEN.
