I've seen a couple of comments talking about how unbalanced Homeworld 1 was but I don't recall it being that bad. I don't think saying most or even a large percentage of units were too specialized - going through the unit list, scouts, ints, defenders and bombers were all commonly used, corvette walls had lights, heavies, and multies, all the frigate types were used, and all the capital ships were used. The race-specific ships I remember Taiidan being used more than Kushan. That leaves minelayers, and the utility ships at the bottom of the build manager, which, granted, where less commonly used and more specialized - but the same can be said of HW2 minelayers and utility ships. I have no idea what you mean by "freeing frigates up from fuel duty" as frigates have never required fuel. I would actually argue frigates were more useful in HW1 due to increased survivability, firepower, hyperspace independence, and the ability to execute meaningful combat maneuvers (in the Homeworld archives somewhere there is a great thread debating the relative strengths of ion frigates versus assault frigates - ICFs obviously had more direct firepower but microed AFs could stay on their flanks out of the ion's firing arc)Also i'm gonna pitch in on the whole debate and say that mechanically HW1 was utter garbage. There's was very little redeeming about it in comparison to Cata or HW2. Both of the latter take HW 1 and give it the much needed slap up the back of the head it desperately needed. HW1 had so many unit types that where useless or highly marginalized it just wasn't funny, and whilst fuel and formations with strikecrafts sounds cool, they rarely brought anything meaningful to the gameplay, (formations with bigger craft are another matter however). By freeing up frigates from fuel duty they where able to push frigate importance much more thoroughly and the lack of rigid formations freed strikcraft to act like the small zippy things they where. The addition of squadrons greatly improved ease of use as well.
