This has been a debate over the past several years.
I don’t know if you can do a search (im too lazy) or if the threads are still even here. With all the new updating of the boards.
One solution that was brought up was, just adding the fuel leak between the ranges of 18k through 30k. We'd be able to distinguish a box formation of bombers opposed to 4 fighters.
Leading to, hmmm.. if I knew it were bombers (do I ReAllY?!??) want to climb to them?! Fighters, I'd Probably turn tail and run.
Then again, I think HT just doesn't want to deal with them right now, with tod coming out. I'd want all their time spent there. Then again, that’s just me.
