See brother, many ppl play at night after work. So they will be relatively more comfortable if the attack bases have monotony. U get adjusted easily. If the bases have varying backgrounds it gets irritating.
Like I for example, look for some basic things when attacking like the position of defenses. For me n many others, switching the view will only become tiresome n ppl will complain. So, I say let it be according to ur time zone. It'll be easier to implement too.
