Not sure if you are 'scrolling' the map by moving the cursor to the edges of the screen, or if you are using WASD to move the map around. WASD is by far the better option.

Also, you can speed up the scrolling in the Options menu.

Finally, probably the best thing is to click in the direction of the crystal to get your DG moving that way, then scroll over to the crystal and click on it.

I suppose but I agree with the poster the minimap gives you known, constant locations, zooming out is great to see if you have help coming, but I'd like the INSTANT-ness of the right click map function.  That being said I am dealing with it like everyone else and clicking run away then actually finding the place I really intend to go.

I find easiest way to move the screen is with zoom out, and zoom in on the spot you want to watch.

The strategic zoom would understandably take some time to adjust to, for non-SupCom players. I've played both SupCom and Dota and I'm ok with quickly zooming out and clicking on the place I need to go. However, I do admit that zooming out and clicking is indeed slightly slower than quickly clicking on the minimap, especially when you've zoomed in for spell targetting just before.
