Ice Ram is a deceptively strong Epic Event.
One event to do a wound and force a target is a very reasonable trade in many situations.
So don’t be afraid to use Ice Ram even if you are only getting one trigger.

However with Svara's ability, Ice Golems and Glacial Shift, you can do the effect multiple times in the same turn. Remember you can Ram your own Ice golems to move them further before moving those golems, giving you extra range if you are willing to damage them.
To say the least, the value she can get from Ice Ram is really off the charts.

Trying to setup at least one big Ice Ram turn is a big part of the gameplay of Polar dwarves. This turn can be game shifting and the kind of turn that put the Polar Dwarves in a favorable position.
