Act II mercs

[Vash]

Holy Freeze is over-used.  I prefer Defiance personally.  Get some High Defense armor for you and especially your mercinary and if you get iron skin high enough, you'll only have a 5% chance of being struck, even in hell.  This, IMO, is far better than Holy Freeze.  Why slow down damaging attacks when you can avoid them all togeather?

Might is also a good choice if you have some good gear for your mercinary, however, as someone pointed out, he has the tendency to get stuck IN THE MIDDLE of a pack of monsters when your moving through which is usually determintal to his health.  And in cows, forget it...  But on the plus side, he'll make a great boss killer  :D

I like Holy Freeze better than Defiance because in order to make good use of Defiance, you'd have to go out of your way to find items with (at least slightly) higher defense. You don't need to do anything special to use Holy Freeze. Just use it =)

Another thing is that your defense goes splat when you run whereas it's beneficial to run with Holy Freeze on (run out of range before being attacked).
