Aren't this kind of system the same as FFXIV? But instead of giving commands to 4 characters you give to 1. This could be considered as button spaming as well, Yet no one complained - people liked it.
I liked and love the current battle system because it gives me that feeling you have from that old final fantasy games, like the one presented on movie, and many other ones (from 4 to 7)
PS: There was tens of thousand battles in those old FF's on world map for example that you go throuhg Fight/Magic selecting the same skill/spell all the time. That wasn't bad.
EDIT: Found some good old button spamming FF style xD
