While we w8...can someone either link me to a good modding tutorial using any modding program (I have XSI SofImage ModTool 6), preferably the easiest actually
or towards an already existing good mod (the ones you use) to SoaSE (but not 7 deadly sins...)! PLEASE!
1) Also for your XIN ships or any other race, I was thinking about introducing the Infiltrate ability which would allow any ship (to a maximum depending on research level) to be regarded as friendly by the enemy, thereby allowing it to actually join an enemy fleet and conquer with it! The difference between this and camouflage would get a bonus upon attacking that specific fleet after a certain amount of time. For example, at level 1, the technology would confere to you an extra, let's say, 75% damage for 120 secs, on every single ship located in that fleet!
Technically it would mean sending, let's say a frigate into a system WITHOUT ANY ENNEMIES IN IT, and activating the skill would camouflage the ship as being derelict, when an enemy comes by the ship regains activity and sticks to the group! Then when you feel ready to engage, you send YOUR fleet against the target and when the battle starts, you deactivate the skill, thereby granting your fleet the 75% bonus for 120 sec (which should be enough time to make considerable damage).
2) Second concept is the good old FIRESHIP. an extremely fast and light (i.e. CHEAP) vessel charged with explosives. Like a mine in a way but mobile and it's blast would create A.O.E damage to any ship located in a certain radius (friendly or foe)! Meaning the ship needs to be used prior to combat as a sort of primary offensive to weaken the enemy.
A strategy would be to designate your Fireship as an infiltrating ship and detonating it prior to your fleets arrival on the enemy flagship ! THE CARNAGE 
3) You wrote earlier that Xin ships were slower but more heavily armored and thus had a significant boost in price. Right? In that perspective, how would a mobile repair platform sound? Either as an independant ship or a class ability (which would have a long cooldown time to avoid abuse), it would allow to deploy a mobile repair station which would well....euhhh.....repair ships (at an extremely slow speed) but that cannot be deployed during combat. Meaning you would need to carry multiple on your fleet during raids and invasions as back-up and alternate ships during battle...
Well that's some of my ideas, I hope I'm staying on subject
! Please tell me if you find this usefull, or you would just prefer if I were to shut up
! Now at least I can say I gave my 2 cents worth of help (love to give more though)!
