Abaddon, A lot of things get less complicated with advanced tools. Like getting the exact color of things, mass-selection of single colors, removing nasty anti-alias (instead of manually redrawing over lines; this also reduces filesize), layers for avoiding mistakes, and many, many other things.
You see, advanced tools weren't made to make things harder--rather, the reality is quite the opposite. If it weren't, we'd still be in the stone age.
Case in point: Symphony D.'s citied map. I dare you to single out the cities using MSPaint only.
