Well I definitely don't appreciate the sarcasm in a thread that is meant to promote constructive thinking
Ah, that's because the matter square or hex had been settled some time ago by a decree from the highest authority (ie. Frogboy). 
From here.
Even with the innovations,
Elemental is stubbornly traditional in places. "I hate hexes," says Wardell when asked
what he thinks of Civ 5's big new feature. "One, I like being able to move in eight directions. I don't like only being able to move in six. Two, it makes the game feel like playing on a hardcore board tile game. I just don't like that look."
From here.
I personally agree with you about hexes and of course about Battle for Wesnoth, beautiful and fun game. But there is no chance for Elemental getting hexes, so not much point in discussing it (it got discussed to death over a year ago), and one can still have a good game with squares.
