your opinion of what is and is not aesthetically pleasing means about as much as mine does. maybe less, considering i don't claim to speak for anyone but myself out of some sort of inflated sense of self-importance.
the way i see it, the flat yellow was not particularly aesthetically pleasing and the more neutral silver suits more card frames than the old borders did. change really isn't the end of the world and there's no need to flail around trying to make anybody who disagrees with you appear particularly deranged for that difference in opinion when that opinion is "liking silver card borders more or less than yellow"
