Just need to remember,

do points in regions leak?

such as Random point in region.

do i set it to a variable first then order a unit to that point or can the random point in region function work by itself leakless?

i'm pretty sure it'll leak. the only way i can think of to get a random point is to generate a random x and random y coordinate inside the region's boundaries, and make that into a point. if you know how to use jass, you don't need to make point variables since you can do what i said above and just save the coordinates instead of the point variable.

Edit: okay i'm pretty damn sure regions are just 4 real values: minX, minY, maxX, and maxY (and possibly centerX, centerY). so, they do NOT contain ANY of the points located within their bounds.

Yep, it leaks ^^
Instead of using reals (which you indeed do not need to clear, since they don't leak), why not use a TempLoc-variable that sets to a random point in your region and remove it afterwards? =/
Seems easier...

strange, ive always known it was a leak, but i've looked into line tower defense, and they never use variable clearing, and i don't remember any lag at all.

Well, some tiny point leaks won't create huge lag from the first minute nor 10-minutes of gameplaying. They still fill up bits of memory, until the lag comes up. It's still a point, isn't it?
