Old design, that just didn't age well.
The only map that is good, and I mean, far away in a class of its own, is Ovoo map. Ovoo map is the right mix of jumping around, getting into engagements, interesting terrain, etc.
The absolute worst map in this category is Catenaeu flats.
It's awful, downright, obnoxious. Running from point to point, then up to a hill, then down the hill, then up the hill again. It's practically aimless, the mechanic of blasting pve nodes isn't fun, it needs to go. It's an exercise in tedium.
What I dont understand is that while the game has seen improvement in different areas (though arguably, there's no real progression in this treadmill fest), pvp frontline maps have continued to be terrible, and will probably continue to be terrible because square isn't known for accepting change very well. They'll sit on a terrible mechanic for half a decade in sheer stubbornness and disdain for its fans.
I'm done ranting now.
