In my opinion, pass distance AEQ are useless as I have seen QBs with relatively low strength (48 or lower) throw 60-70 yards. I think the sim has it where all QBs have unlimited amount of range, attributes just effect how accurate and how fast the ball moves.
And with the state of the sim, long passes over 30 yards are so, are not really effective this season.
You will do much better with an AEQ with pass quality, or SAs like TS PF FG or PP. I know from experience how much of a pain in the ass finding a decent piece of AEQ with additional attributes on it (I settled for a piece with TS and +2 stamina)
