Proposal for an update...

By that logic, why not just do

{{MainStreamQuest
     |Image1= [[File:insert_file_name.png|50px]]
       |Name= 
   |Briefing= 
|Instruction=

What I'm trying to say, is that you're missing a very obvious point that I've been making.

What's the difference in output between the code on my subpage with the documentation, the one that you typed in the above post, and the retarded looking pyramid I typed earlier in this reply? Absolutely nothing; it's a matter of personal preference and being consistent. You could even call the template from one line like this:

{{MainStreamQuest||Image1= [[File:insertimg.png|50px]]||Name=name||Briefing=briefing||Instruction=instruction|}

and it would still work.

Oh and...this topic came up in the past. That format you typed it in is considered difficult to read by some too, so it can't just be based on your opinion of what is and isn't easy to read.
