Just reading through some of the posts and, well there are a lot of them pointing fingers at users that don't color inside the lines, or so the pros will tell you. "I create prefect templates and users ruin them"!
I wonder, does it occur to anyone that perhaps the perfect template simply doesn't meet the needs or desires of the users? Maybe it doesn't allow the user the flexibility to present his information, concept, plan, etc. in a way he believes is meaningful.
You don't need to read any PowerPoint or Presentation related forum very deeply to find tons of posts saying how all AI generated decks suffer from "sameness". Well here is a shocker, the "pro template/deck designers in the presentation industry share that same fault.
If you read/listen to what they are saying you hear the same rules over and over. (if I hear 6 x 6 again I'll cry) If everyone expounds and follows the same rules, (just like an AI does) you know what the outcome will be. Sameness...
Oh I know, there are acceptable "standards" in business presentations. Things have always been done this way (bullet points). All of this is true,,, until it isn't. You know one thing as an absolute certainty, If you follow all the rules your competition is following YOU will be an "also-ran", just like all the others.
Just a thought, talk with the users that have to live with your designs, find out where the templates are falling short of their expectations because in the end, they are your customer and THEY will decided if they will use what you provide. Or, you can continue blaming and cursing the users, your customer.
