All of the instrumental changes he mentioned were for the better, and eventually the band from 1977 through 1979 was the best it ever was or would be in terms of playing capabilities. One of the tops of any rock band in fact.
This album isn't really very bombastic tbh. Like half the songs are acoustic strumming and and the other half are complex hard rock. Bombast is like Kansas, not ####ing Jethro Tull lol. I could maybe see APP being "bombastic" but still...it's no Tales From Topographic Oceans. I guess this is just opinion though.
