Howdy! Long time homeworld player here, even played some complex 8 and 9. There are a few balance issues that I have noticed just in the games I have played already, and it appears others have noticed them too. The units are pretty balanced for the most part which is really encouraging to me, and great job Gearbox for bringing this IP back to life!
Homeworld 1 races have instant access to Hyperspace, without the need to build a module. This is a huge tactical advantage to them and allows them great early game flexibility, as the HW2 races must build and research in order to jump. I used this to jump some detroyers in my brothers base while he was on the other side of the map and killed his mothership before he could recall anything big enough to take them out. An easy fix for this would be to make a research tree and hyperspace jump array similar to the sensor array that allows jumping for the HW1 Races. Or keep it how it is and figure out a way to asynchronously balance that.
Homeworld 2 races can build shipyards, and HW1 races can’t. This is really a huge issue in mid to late game, as it allows HW2 races to outbuild HW1 races in the heavy classes (Destroyers-Crusiers). An easy fix for this could be taking the scaffold from the first and third single player missions and creating a “shipyard” for the HW1 races with it. Also there are some iimproved manufacturing research techs that HW2 races can use to build faster, HW 1 races are severely lacking this.
FIghters in squadrons vs Fighters out of squadrons. So far I have seen a few people complain that the HW 1 fighters are horrible compared to equal numbers of HW2 fighters. While that may be true, I have seen lately that the HW 1 fighters actually are better when used in conjunction than the HW2 fighters. HW1 Defenders are nearly as good as corvettes at killing fighters. Furthermore, it seems that fighters from HW1 have and advantage versus fighters from HW2, because they are not stuck in squadrons. Each individual ship maneuvers freely and as the enemy squadron tracks down one HW1 fighter, it misses the other 4 that wen’t different directions. This allows the squadron to focus fire one enemy down, but after that it is outmaneuvered by the rest of the HW1 fighters. An easy fix for this would be to put all HW 1 fighters in squadrons as well.
Thats all I have for now. More to come as I play this game more!
