Sadly, I now think they are overpriced with the reduced 15" range. Maybe they were simply too good before ?
They might still hold a place in an army but only against certain enemies like Dwarfs and Humans. They are capable fighters and their initiative of 4 holds them in good stead against many opponents.
They are however, as they always have been, rather vulnerable to missile fire. I wouldn't take them into combat against any kind of Elf army or an army I thought would be using a lot of missile troops unless I was confident I could shield them as they slinked across the battlefield.
If you can get them into the enemy lines or around the flanks you could be rewarded because they cause fear.
3 salamanders together will give you a unit strength of 18, just about enough to worry your opponent after he's taken a few casualties.
Use them as support troops not as a core attacking unit.
If you choose to use them, don't take a unit of one ! Take a full unit of 3 because you'll probably need those extra wounds.
Overall, I do feel they are a touch too expensive though. 55 pts would be nearer the mark in my mind.
