I think the can of worms was opened when the thread was posted
) but it was going to be.
But it has started a good debate and so far all pretty lighthearted and down to personal opinion, which is great.
I saw the initial post as a question to cheating in figure (paint), so my comments on decals used etc refered to that.
Maybe I am a traditionalist, although not too old, and the enjoyment for me is painting the piece and trying to push my personal boundaries with a brush even if the result would be better with decals etc, but that is only my way.
The debate of passing off in competitions and guidelines is fair a whole field on its own.
At the end of the day and as said, use whatever you feel like using to get the result and/or the enjoyment you want from the piece either during or as a finished piece, and if you answer honestly when asked how you did a particular part, that is a bonus
All the best
