They're better on 2nd ages since they give a larger dps buff (up to about the level of a 1st age iirc), but it's free dps/healing/etc. why would you not get them? If you want to be even more OP as a freep, get them...
First age hammer went from 149.7~>152.0
Second age sword went from 121.0~>131.0
Don't bother if you have a FA. Waste of time and money.

Get them no matter what type of LI you have. It's still a DPS buff on FA, so why not? You don't have to pay TP for them if you don't want to. My SA bow is really enjoying its massive DPS buff against creeps.
