Currently there is a large imbalance between HVs and SVs, as well as with the SV as a whole. In PvP SVs have always been a pain to deal with, since their small size and quick movement makes it hard to hit them. The changes in A9 have only worsened this problem, as the nerf to rocket speed means that rockets can no longer even somewhat consistently hit a fast SV. Since rockets are the main way for HVs/CVs/BAs to hit moving targets SVs have become incredibly strong in both atmosphere and orbit, as it is practically impossible to get enough damage onto the SV to disable it as long as it is piloted competently. The SVs high mobility combined with its slow projectile weapons mean that SVs struggle to kill other SVs as it is also extremely hard to hit another SV and is usually down to just luck with homing rockets. These factors combine to mean that SVs can easily kill BAs, CVs, and HVs while SVs cannot be easily killed by HVs, other SVs, CVs, or BAs. Also, in late A8 the HV was sitting at a fairly good position balance wise, where HVs would serve as the main attack vessel on planets with SVs to support, and HV duels would be fairly short compared to SV and CV duels (15-30 minutes vs 1 hour +). If anything the HV could have used with a buff to their damage as they were already being replaced by SVs as the main attack vessel due to how strong the SVs increased mobility is in almost every situation. However, in A9 for some reason HVs were significantly nerfed, with HV rockets going from 1170 damage to 500, along with the massive nerf to rocket speed this led to HVs becoming effectively useless in PvP. The decrease in damage means that HVs, which were already being out shined by SVs, are now pointless to bring to attack BAs. Also, the nerf to rocket speed means that HV rockets (which already missed moving targets sometimes) now miss over 90% of their shots even against other HVs, and can almost never hit a moving SV. This combined with the new thrusters for HVs means that HV duels can now also last for hours, as most of the shots miss and the few that do hit do barely any damage. With the addition of shields in A10 there is a good chance the SV will end up becoming practically immortal, where a brick of thrust can just use the shield to absorb any shots that do hit while dodging 99% of incoming damage. One solution to this would be to increase rocket speeds back to what they were in late A8, or even making them faster, along with increasing HV rocket damage back to at least 1170, if not even higher. Also, SVs could either have homing rockets significantly buffed to make them hit much more consistently or be given a new weapon specifically meant for SV v SV duels. This would allow SVs to be more easily hit by all types of ship which would make combat much less frustrating along with shortening duels as a whole, as shots will hit more frequently with faster rockets, and as anyone who has done a large of PvP will agree with, long fights where nobody hits anyone aren't very fun for either side.
