A little Test you can do:

 

After a game is released, take notes on how long spells last, what items are being evolved over to level based and bind on equip/pick up, and keep notes on each spell and ability you have.

 

Over time, you will always see a change in the duration, area of effect, etc., and not for the better. You will also see that, where you once could play solo, you can no longer do so.

     If you pay attention, you will realize what is happening.
