Any source for this claims my books show the contradict,
Check any book containing the number of sorties and losses suffered... loss/sortie went DOWN for the LW bombers, loss/sortie went UP for RAF fighters by September. Essentially the concentration of fighters and bombers instead of sending them in piecemeal worked well (rather predicable).
Galland and pilots may have not liked the new tactics (what about Mölders BTW? he was a much more established and systematic officier than the charismatic Galland), but apparently he was a big enough character not see any further than his own tactical needs and kept blaming Göring for it.
Its a pity that only his version survives of the events, isn't it.
LW fighter losses increased dramaticly, LW bomber losses remain constant and RAF fighter losses went down (especially the Hurricane).
So if RAF fighter losses went "down", why were Park and Dowding so worried by September? Why were aircraft reserves dwindling? (See official RAF history of BoB for figures)
Also show us your sources to your claims of that "dramatic" LW fighter loss increase, please...
