In risk of getting too serious, I'm more comparing them to the nature of large capital ships, especially Battleships, and how they actually were not effective at war for the costs inherit. Their very nature means that they're prone to become too expensive to risk in actual batter and are not expendable. There's a reason there's very few large capital ships in existence now and no battleships anywhere in service in any navy (last was the USS Missouri which spent the Gulf war I mainly launching cruise missiles). The few large ships that are around are namely carriers and are designed to be a facilitator of a completely different, generally cost effective and more importantly, expendable (in comparison to the ship itself) weapons system (fighters and aircraft / missiles). You're simply better off having a bunch of smaller vessels as they can be in more places, attack more targets, faster, more flexible, etc. Also as cold as it sounds, EXPENDABLE (GRF class carrier is what? 13Billion...
each, while an Arleigh Burke Destroyer's...1.1ish?). L4, you probably know, weight in

EA actually takes this into account rather well with the activation/formation system and the inherit limitation on attacks targeting a single formation at a time. A warlord versus most other formations (outside of the equivalent counter from another faction) generally isn't as flexible and effective as other cheaper alternatives en masse. Warlords exist to counter other battle titans who are present because you've got a battle titan... yada yada yada

Yeah sure the Imperials will work a world to death, I've got no doubt about that. Still better from a logic and effectiveness standpoint to simply conscript the population and use them as cannon fodder or work them to death building 100000 times the number of tanks and APCs (and then conscript the surviving workers

)
So yeah... let's not get logic involved here... I like big stompy robots and the rule of cool they represent
