ok, here it goes. i'll just make a list of all weapons in SE
NORMAL
APB - this weapon is almost fine. it is a general all-purpose weapon in the game, and is outclassed in different areas by other weapons. it however outranges most other weapons. the range should be capped at 6, and base rad cost doubled.
CSM - ehrm, the weapon is fine. it is however easily shot down by PDC - which should be the way it is because PDC are the only counter you have.
It could use a 10kT reduction though.
MB - the only thing is adding another 5 damage points to it, making it +5 per level instead of the current skipping of the damage addition at 2nd level.
Torpedoes - now that is a whole different subject. That is supposed to be the main weapon of capital warships. The damage 100 is good. Range should be increased to 8 and a +20% accuracy to anti-matter and +30% accuracy to Quantum. +50% cost because the weapon becomes very powerful.
Plasma Missile - absolutely fine in my book - only thing is it realy requires at least some defense against PDC - 5% ECM per level?
PDC - thats a tricky one. i'll leave it for later because it needs some testing.
Plague Bomb - okay
PPB - -10 all damage, and thats it.
WMG - fine
TPC - with its high cost and reload time it should be a viable weapon. +10 to damage.
ID - i think its just fine the way it is. It should not, however, be possible to mount this weapon because a heavy mount simply destroys ALL engines.
Ionic Pulse Missile - a big question? it should be made to do exactly 120 damage to destroy all engines - to compensate for ID. Perharps extra speed or ECM bonus (or both) to make it more viable as a weapon.
PN - completely fine
NB - completely fine, though it might be moved down the tech tree, to go along the PN and RB.
RB - absolutely fine
Smart bombs - no complaints whatsoever, a good weapon for high costs.
Repulsor - fine
Tractor - fine, though a longer-ranged, less-potent Version as suggested before is good
GH - another big one. Personally i think its an average weapon, all it could use is a mediocre to-hit bonus of, say, 15%-20%
Wormhole beam - too high on research tree! physics 4??!! how about Astrophysics 3 instead?
SDepleter - its a good weapon! should however have a slight to-hit penalty to compensate for extreme damage. or double kT, with a non-mountable Version of it as-is.
SDistruptor - im sorry, but this one is completely useless - only good in point-blank. current damage is 60-45-30-15. How about 80-60-60-40, and without mounting?
Boarding - fine!
DUC - fine!
NSP - well, the gun is okay. i'd like to see at least a 10k research base for it. whats that, it is easier to research an NSP than a meson bLaster???
Alternate Bombs Idea: you get Napalm with the vanilla tech tree. from Physics 1 you get rad bomb on levels 1-5. from Military Science 1 you get Neutron Bomb on levels 3-7. From Computers 2 you get Smart Bombs at levels 5-7.
RACIAL
Organic
Plasma - good
Lightning - good
Parasite - good. should get half the bonus of CSM
Acid - unlike Torpedoe there is no reason for seeking here. However it might be more destructive - how about +50% damage?
Crystallurgy
Shard - well, its a general weapon. its good enough, but could benefit from +5 damage on all levels.
HEM - pardon me? give me one reason to choose this weapon over its alternative - Tachyon Cannon. how about Quad Damage to Shields? also a to-hit of +10% would do good to balance this gun out.
Crystalline Torpedo - the best solution i can see is double/triple its damage resistance. 45 damage is not much.
Energy dampener - fine
Temporal
TDB - a fine weapon!
Temporal Shifter - good, but a fine racial weapon
Shield Accelerator - while a powerful weapon, it is not much better than SD and more difficult to research. aswell, a good thing for the 1500RP
Tachyon Cannon - a fine gun there
Psychic
TKP - debatable, but a fine gun
Mental Flailer - a fine gun
AS - debatable. i say leave it as-is.
MSG - a fine gun
Religious
Talisman - a very debatable topic. i'll give it more thinking and post something tomorrow.
