Perhaps your opponent should be building troops of his own? I mean, would you call it "cheap" if you attacked his systems and glassed his planets without issue because he had no ships to oppose you?
EDIT: and yes, I realize this is an AI issue in that case.

I was going to suggest AI issues seeing as I don't PBW. It makes it kind of a deal breaker for me to buy the game if the AI can't build enough ships to fight me.
Also, the reports of 50 troops being contructed clutter the news.
I find that my ships refuel in enemy systems off of enemy resupply depots.
I still maintain that troops should be treated more like ships than fighters. The quantities of troops that can be easily landed on a planet brings my system to its knees, often causing the game to freeze, and is rarely necessary anyhow. I say make them cost ~3 times as much and weigh ~10 times as much. Giving weapon platforms the ability to hit ground troops at ranges and damages far exceeding them would also make things a lot more interesting.
