Okay. My strategies are for the Midway, and it assumes you have gotten a full Klingon techtree with HWP tractor beam for credits, and for Borg, fusion cube and 2 transwarp gates, + full techtree.

You initial base is where most of your heavy capitol ships should lie. Negh'Vars and Assault Disruptors are the best heavy hitters. Smaller ships should be K'Vorts, that one with the micro-photons and B'Rel. (Cloak makes an excellent flank tactic) I use strategies by cloaking 2 squadrons of K'Vorts and B'Rels and moving them behind the enemies, while Negh'Var and Assault Disruptors brawl with the fleets. If you have a transwarp gate, Gate in some tactical cubes and regular cubes, if you have them. Decloak the K'Vorts and B'Rels right behind the enemy fleet. K'Vorts fire their shield breaking torp into the heaviest enemy cap there (Fed = Descent, Galaxy, Nebula, Steamrunner, Sovereign, Defiant Borg = Fusion Cube, Cube, Tactical Cube, Diamond Klingon = Negh'Var, Assault Disruptors, Vor'Cha) B'Rels decloak after the K'Vorts shields return, and add their firepower to the chaos. Send a half group of K'Vorts to cloak and go to the enemies strongest flank. Pop their shield breaking torps into the heavier caps there and attack. Cloak is your friend. Also, have about 6 HWP constantly tractoring to a halt the heaviest or fastest cap there, allowing them to eat torp after torp after torp. Akiras are REALLY dangerous in numbers, with their Chain torp They let it loose, and it hits every single ship in your fleet.

If you can spare it, make a transwarp tunnel on the enemies flank, and send an attack fleet there, You will have sandwiched the fleet there and it is dead. Assimilate at leisure.

Also, I use the chaos of the battle to transwarp a strike team in to capture a construction ship and run like hell. Usually, a squad of Negh'Vars, tactical cubes, 1/2 squad of Fusion cubes, and some Assault Disruptors are great for that. Transwarp them in on the side where the enemy has no defenses. Assault disruptors take care of turret defenses, while the heavier caps pound on the outpost. Disable it's weapons ONLY. Once weapons are down, hunt tech. Popping a tech is a great way to slaughter  human players, although it barely taps AIs. Destroy all buildings except for outpost. Order all ships to beam crew aboard. Take the outpost, and build tech tree at leisure.

Ownage

i thought that the akira still had chain reaction pulsar and the galaxy class has point defense

I didn't ever like the CRP, not strong enough to consider using.  Point Defense on the other hand...

i remember researching point defence in b1 and it did almost nothing it was so anoying paying for sumthing then finding out it has no use!
