I dont know why you would want to use a faith or a frost maiden, look at ice and its pretty much specifically built for this skill build. For my merc though, im going to use an act 1 fire arrow with faith fortitude and andariels visage.

Those 2 things on the Ice runeword make it more powerful than just the +2 skills of Faith.
If you want to just freeze enemies and then Strafe them, then only put 1 point in Freezing Arrow. You aren't using it for the damage any more, so there's no point in maxing it. You wont technically be a Frostmaiden any more either, you'll be just a normal Strafer.
A Frostmaiden uses FA to do the most of her damage, and Strafe as a back-up skill to leech back mana, and trigger the Level 22 Frost Nova On Striking all over the screen for mass slowing.
Damn, now I'm even more undecided as ever. Can an act 1 Merc use a FAITH in a GMB? I've already got a Faith GMB and would hate to not be able to use it now.
This is only my opinion, but I will post it anyway
I think faith is far superior to frostmaidens who use strafe as a secondary attack. Ice has way too low physical damage to use strafe effectively, while using faith gives you huge ar, huge damage (leech, which is important!), and almost (if not all) the required IAS to get Strafe and Freezing Arrow running, not to mention that the Fana will boost your merc too, killing his attack speed tremendously.
Just put Infinity on the merc and you will be dishing far more damage than any other combination already mentioned, and Ice becomes fairly poor option from this view point. Granted, a rogue merc probably survives better, but still, infinity + faith all the way. This combination also makes you better suited to take on bosses, since ITD does not work on them. Using faith and Infinity makes your AR problems vanish in a heartbeat, even when using strafe and having just one point in penetrate. End of rant. :wave:
Because Freezing Arrow is better for PvM than strafe, espescially HC. It really does some nasty damage once you pump it up and with Infinity the damage goes Skyhigh it's insane. You'll kill a lot faster with Infinity than pride, as the strafe is only the backup.
Also that faith on switch is a great idea, while using Ice the main bow, if you don't happen to have Cta. That way you can have maximal FA, while still getting great strafe on switch.
