The thing to remember is war-gaming standard and modelling standard are vastly different. On the one hand you want to create reasonable size armies for the purpose of miniature warfare on the tabletop in as short a time frame as possible so such things as unit numbers on helmets and piping on collar patches are a bit a waste of your time as they will hardly be noticed when looked at on the table.
On the other hand if you are painting a handful of figures for a diorama or for other viewers delectation then these finishing touches are essential and the enormous effort required to get it right is countered by the small numbers. Personally I cant paint much better than wargame standard and frankly few of us can.
If the figures are for wargaming then focus on the gaming and not the colour of the piping on the Colonels cuffs.
Maybe I'm the only one but I'm wargaming with the highest quality of painting, I can't enjoy the game if everything is not perfect, or at least very close to perfect. (nobody is perfect).
My life could be easier if I was not always running for something better (human nature), for example I already painted different entire armies in the past but because I upgraded my quality of painting I have to paint again another full army with all the details and quality I forgot the last time.
When It's about a small diorama with ten figures it doesn't matter but when it's about armies of Thousands figures, hundreds vehicules/wagons/ship or planes...
And I will never be satisfied with an ordinary quality, the best or nothing, it's a curse but a delicious one
I noticed on ETS that some diorama builders with a beautiful painting are not removing the mold line, it doesn't matter with an ordinary painting but it really spoil the result when the painting is so good.
