Dom pushing as a weapon and dominion kill as a strategy are not the same. For example you can dom push to boost morale, leverage immortals, wreck economy if your enemy has income scales and to push a specific dominion bonus like abysias fire power, niefels cold power, Agarthas statue hp bonus etc. If you can combine more than one of these benefits it can make dom pushing a part of your core strategy.

So there are many cases where dompush is a devastating weapon besides going for a dominion kill.
