Your character essentially still moves like a tank, which also limits the amount of aggressiveness you can give the enemies, you can essentially still require stop and pop while updating the movement system in RE because right now if you up the speed on the enemies, running away from them and maneuvering is not an attractive option at all, you still can't keep shooting while backing away, there's still no side movement, however slightly, and no RE4's control scheme is not perfect, it has never been perfect, it can always use improvements.
Nobody is saying Redfield needs to run around like a Niko Bellic or Nathan Drake, but the player character in RE5 can use better mobility, maybe a little more mobility than the guy in Dark Sector, ESPECIALLY when enemies are throwing objects at you, there is such a disconnect between the level of mobility in a cutscene in RE4 and what the player is actually given. Things like allowing the player a button to vault over objects or leap over gaps on rooftops WITHOUT HAVING TO WAIT FOR A BUTTON PROMPT while being chased would be great, a melee button would be great. We're not dealing with the GC controller anymore, you have more buttons, make use of them.
