I haven't played AH2 online, so I don't know how GV's are currently displayed. If it's anything like the current version of AH, I can see where you might be concerned. Those dots can be seen from a looooong ways off! Add to the fact that anyone can clip the visual range of terrain details, and I will definitely agree with you: it'd be hell for the GV drivers. Everyone in the air could see 'em, regardless of where they were or what they were hiding behind on their FE.
The main reason I ask is that there's already something like your probable scenario in the game. Above 2,500 feet AGL the terrain cover vanishes, exposing any GV that's running around. Only when you dive below that altitude can you find out if he's hiding in a barn or in a house. Unfortunately, that's also the problem. I can agree with cutting the trees/shrubs out above a given alt to save FR, but it creates the problem of letting a player see the GV even if the GV is hiding in a bombed-out barn. By separating the two sliders you wouldn't be giving up any more of an advantage to the pilot. As it stands he can probably climb to 2,500ft AGL and see the GV anyway. The trouble arises when you ask everyone to set the Object Size slider to the same setting. Not every system can handle that much ground clutter, plus tracers, plus GVs, plus everything else we see.
That's the primary reason I asked HT to separate the Object Size slider into a pair of sliders. An advantage already exists in that a pilot can climb until the clutter cuts out to spot a GV. So asking for the ability to trim the cover back isn't a major problem. Now I'm not saying I'd like to eliminate it, just have the ability to set strat/field buildings and terrain cover density separately. Basically the same thing we have now in the Object Size slider as far as what it does, only split into two sliders. That way I can get a nice FR, still see plenty of ground cover, and ident strat/field buildings from further than 1,500 yards out. GVs wouldn't lose much of an advantage, if any, because the pilot would still see the same cover in the same place the tank driver does. But it would make flying down low, on a slow system, less like a slider-show. Plus you could actually dive bomb a strat target from higher than 3k.
