Ah OK, well I don't know how hard it is to make it. But I can imagine people buy templates because they don't know how to start making an RTS.
So it would be extra difficult for a beginner to create something I described. It seems to me though, that being able to click on the enemy where your troops will stop at firing distance and attack, is a crucial element to have in the template.
I don't think it even needs to be an 'attack anything on the way' move, C&C1 and RA1 didn't have it either if I'm not mistaken!
Well, it's up to you of course, I'm just making a suggestion. :)
