I've been trying to explain to people about Ion Cannons for a month now that they may be very unbalanced. I play in GSA a lot with SFC3 and one thing I have notice is that Klingon ships with Ion Cannons are deadly. Granted, they are pretty short range (Range 20 weapon, I guess that means 20,000 Km) but they can produce as much damage as a Medium Plasma, take less power to arm then a Quantum, and have more acuracy then most of the other Beam weapons in the game. Ok, Klingon Diruptors and Photons are not as good as Romulan Disruptors or Fed Photons, and I suppose this is Activisions way of giving the Klingons a good weapon, but its too powerful. I've noticed a lot on GSA that most klingons don't even bother with the Photons much, and only install a few light disruptors for long range sniping. Most Klingon players just load a ton of Ion Cannons on their ships for lots of close range firepower. I really don't have a problem for Klingon designers to do this if they want to, but its practically made some of the other Klingon weapons useless. Also, Romulan ships have very poor Armor compared to Klingon and Fed armor. Klingons have an advantage of Fast, highly armored ships with lots of heavy fire power with Ion cannons. A good Klingon player can cause a lot of damage (even to a borg) with these combinatioins to his Klingon ship.
I'm not saying decrease the damage output of the Ion cannon or increase the size of the weapon, I just think a simple increase on the Recharge rate of the weapon would really help balance out this weapon and force Klingon players to use other weapon systems on their ships. Like I said above, when was the last time you saw a Klingon use Photons?
I also brought up the idea before about making Standard weapons have a little more firepower then Fast firing weapons. Why? Because standard Primaries weapons are practically useless compared to fast firing weapons. I've heard people say that the fast firing primaries are already balanced due to cost increase. I don't think that really is enough because they don't cost THAT much more compared to the overall ship cost in credits. I just think a simple solution to this is too increase the damage output of Standards by 25 to 33%. That would at least make Standard Primaries useful for something.
