I used to have a problem with points and getting my seams to match up. It was so frustrating. Then I discovered several things that have changed how my quilts turn out. I became friends (or at least good acquaintances) with the rotary cutter. I use what I call quick piecing, also called strip piecing, whenever I can. I also sew all triangles using the Half Square Triangle method. Now my triangles have points, my seams match up, and life is good.
Are these cutting techniques considered crutches? I would say a resounding NO. Use whatever technique gives you the results you're looking for.
And if a point happens to get cut off, you tell everyone that you meant for that to happen. It's called creative license. :)
