licensure - don't buy unity pro 5 if you don't want to spend 4500

So I have this island project and I liked the water features of unity pro so i purchased unity pro 4 for the update to unity 5. Except Unity 5 reduced its features and they now want me to spend more money on their add ons for ANDROID and IOS. How can I get the free version of Untiy 5 so that I can use it for the non-watered features of PRO?

If i was an established game company whichI will be someday because I am onto new development features. It is such a gamble can i just PLEASE have a trial of the Unity 5 IOS addon to make sure it works?

How can I get the free version of Unity 5?

Unity 5 reduced its features
Did it? Which ones?

Can i just PLEASE have a trial of the Unity 5 IOS addon
AFAIK, there is no such thing as “trial” for Unity 5 or any of its addons, because you already have access to test all the features in Unity Personal. Or are you asking on behalf of a company earning > $100,000?
