First off I would like to say that I love the Galaxy Editor. The versatility of the Data Editor and the Terrain Editor, user-friendliness of the Trigger Editor, the wonderful publishing system are all just great. This post is my humble contribution to possible fixes in future patches.
There are a few areas where the Editor may hold room for improvement. If anyone can correct me on any of the following that would be wonderful. Bear in mind this is in reference to melee map creation and balance.
Ramps: keeping the Protoss happy
Any Protoss player will tell you that being able to block a ramp with one forcefield is essential to some of their staple tactics. The ramp must also be large enough to move a small army through with relative speed, this 'perfect ramp' is the smallest that can be applied to a diagonal cliff section. The closest options for a perpendicular cliff are one smaller than this (that only just squeezes an Ultralisk through) and one larger that cannot be blocked with one forcefield. Of course the grid that we work on is square and squares are wider on the diagonal than the perpendicular.
I am suggesting that the diagonal size ramps should be buildable on perpendicular cliffs and vice-versa, this would mean no changes would be necessary to the current map pool. Pathing and the build grid link directly to the editors grid and that would cause problems if trying to accomplish this but if it is possible, it should be done.
Also, the ramp tool is clunky: with manmade cliffs one can usually learn where to click to successfully place a ramp but with natural cliffs this is not so easy and often I will be clicking away trying unsuccessfully to place a ramp until suddenly I place one double the size I expected.
The level of ground at the base of the ramp must extend back behind the base on either side (by 2.5 squares to the rear and one square out to the side). As far as I can see, this is completely unnecessary and limits the intricacy with which ramps connecting multiple cliff levels can be placed.
When using the copy and paste tool on terrain containing ramps, these ramps will more often than not become bugged, enabling units to path the cliff just to the side of the ramp. This means that every time a ramp is pasted, it must be deleted and replaced. This problem can be solved with a function tool that removes all ramps on the map and replaces them with one click, a 'ramp debug' tool.
