When I explain to new players why past tense is important I usually describe Mizahar as a book, and in order for one's story to fit seamlessly into this book they must write in the same tensing as each other chapter, each other character. Thus, WEATHER past tense is superior or not is far less important than fitting each and every character into the tapestry, the novel, which is Mizahar.
P.S. I don't read XD You can learn to be creative, and how to write without reading. That said, I am sure it helps. Even if all you read is other people's posts though, through practice you will improve. Just keep it up, and get an idea or what your goal is
Try to find a player/character you really admire and find out what they are doing that you aren't. What do they write about that you don't, or what do they leave out that you spend time on? Try out different styles, even if it's a botch you'll still learn something <3
Peace
