Yes!
I'd go so far as to have just one "damage dealer" spec per class (and only one "healer" spec for priests). Put in more talent rows to allow for some customization. For healer priests for example you could have a talent row or two that lets you focus on either sheilding or direct healing.
Blizzard did a bold move when they scrapped the old talent trees. It's time to refresh wow and make another bold move and scrap a lot of the specs.
