Ok, then here it is again: I made special weapon form the Artillery. So you can't use them as "cloaked ship detector", or use them to block enemy space routes. So if you want to find the cloaked enemy you always need a few ships Tachyon Detection ability, so you can't just forget about your scouts. This means that the enemy gets an advantage because you can't locate and destroy his cloaked fleet and you can't block his routes. Your disadvantage is his advantage and this makes the game harder - that is good.
