excluding crawlers, who will always jump, it is a fact to say that roghly all of the abnormals are jumpers. there is a slight chance you will find a normal titan in abnormal or an abnormal that doesn't jump. the programming might 'force' all titans on the map to be abnormals and crawlers w/ jumping abilities OR it just increases the likeliness or spawn rate of jumping abnormals on the map.

Heck, sometimes on normal mode I still get one or two jumping abnormals on a few occasions.
