Ok, so I know that age one, attack means far less than intel for a defending hero, but that intel is always a good factor in attacking heroes, but with Age II limited to hero level, the effects of intel were altered (based on previous information I had)

There was a thread around here somewhere that explained in better detail what happens with Age II, but for the life of me I cannot find it.
I can only go from memory which was that intel was only really beneficial to about 110 or so, because after that, the bonus is no longer applied to mechs, whcih kinda satisfies the defence question, but really wanna look at further benefits. What affect does different intel have on attacking arch bows or cav waves, and how will intel of defending hero make a difference with defending said type of hits, or with the different types of attacks.

Anyone got a good brief on this?
