While I don't find it particularily annoying I believe that the tactic of building a radar and then artillery/catapult/nuke creeping is pretty ...meh and balancing them by long build times/costs or even dps output is not enough. It requires a **** ton of micro and guesswork to identify the threat, scout and destroy it even when you are seeing it happening on screen. Time which could be better spent moving big deathballs of units around (i.e. the fun stuff). A suggestion: Radars always show up as full strategic icons instead of generic blips on the map when in the fog of war (once they have been spotted by a friendly unit, f.e. a flyby scout, or another radar). This could potentially be extended to the more powerful artillery structures (possily making them "visible" as icon ONLY once they have fired on a friendly unit to not take away from the suprise-boom factor). Note that this would still require the player to have a radar of their own to see the blips, it simply makes these critical structures quicker to identify in the fury of battle where scouts usually don't last longer than a few seconds. It also offers an alternative approach to dealing with artillery: destroying the radar towers to deny them vision. This allows the player to react quicker to these somewhat cheesy tower creep strats while still forcing the defender into the offensive and leaving a healthy element of suprise.
If there ever was good micro, it is here. You have to micro to correctly build a pelter creep without letting it get taken out by air or land army or drawing too much attention to yourself early with it and doing it as early as possible before your enemy can know about it. As far as the radar itself goes, yeah, it should remember units it happens to see visually and then track afterwards for sure. If a player could do it, the radar should as well.
I'm still waiting for ghost icons for structures that have been spotted. IRL radar is an active system, so there could be a logic to one radar being able to pinpoint another in range. Highlighting radar could certainly take intelligence warfare up a notch.
TBH I think the blip approach is a pretty clever way to keep proper scouting important even in the late game. It would be a shame to impede that element of the match. I just think that its application on radars and artillery structures is a bit op since the tiny projectiles and sticky radars are so easy to miss even when in direct vision until it is too late. I was also talking about the more powerful artillery structures: i.e. catapults and holkins not the brave little pelter. The catapults and holkins are so mean because they are usually entrenched deep inside a pile of oddly similar looking units and "active" scout units seldom survive long enough to get a good glimpse at them in the heat of macro multi-planet battle.
This is a confirmed addition. Ghost icons for structures that have been spotted is also a confirmed addition.
on that note, the current state of radar means that, while you have radar blips, you don't know what it actually "is" until you obtain visual confirmation. so if someone is dumb enough to, say, try to nuke only radar blips... one could potentially fool him with "false" radar signatures using walls....... i might have to see if that works.... on the other hand, orbital radars now give vision as well. so that might not work as intended.
