you should HAVE that knowledge, the sensor data is level 2! you shouldnt even be CLOSE to your enemy before you have sensor data up. let alone them having "20 siege frigs", by then you should either 1) have them on the defensive (if we're talking relatievly early on) or 2) you should have the second level sensor up (if we're talking anything mroe than 30 minutes into the game
beyond that its a matter of just paying attention, no godly might or divine scrying nescessary.
The only reason I am so stridently pursuing this issue is that frankly, this game was fun in beta, but since release, with the appearance of the AI siege spam, it's lost all fun for me
Prof I've seen you a grand total of 1nce during the beta, there are far more experienced people who have been keeping pace with the game and can handle the siege frigs with the ease of a lazy dog shooing a pesky flee. I hate to say it: but most of the people here are newcomers, you need to give the game more than a few minutes pause to begin to develop a coherent strategy.
for godsake, I felt like a complete noob switching over from beta 4 to release, and I'm one of the most experienced players on this forum, following the devs and a handful of other forumites who have not supported your point.
knowledge of betas 1, 2 and 3, even 4 is not enough to start calling this a cheap "OP" strategy within hours of the games release. seriously, look at your DATESTAMP. thats within 20 hours of the games release! even I dont have enough experience with the game to call anything "OP" yet, so lets not go breaking a perfectly fine game because we dont see the light yet.
It's all a matter of strategy. Siege rushes may be powerful against an unprepared player, but they're a huge gamble and are hardly unstoppable. Much like rushes in other games, a failed rush attempt pretty much guarantees your own loss against a competent enemy.
