Easy raid has become complicated, probably (1,4,3)

I believe the answer is:
i dare say
'probably' is the definition.
(I've seen this before)
'easy raid has become complicated' is the wordplay.
'easy raid' can be anagrammed to 'I DARE SAY'.
But, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for i dare say that I've seen before include "It's possible" , "It is probable" , "It's very likely!" , "Quite possibly" , "one might suppose" .)
