I spent last night whoring it up in aircraft on the Legion of Sparta server. Never once did I feel like I was ever in any danger. My Shiva got close to being shot down. Not ONCE did my LRM Hawkmoth ever end up in any danger. I ended the game on Extremity in the exact same VTOL I started the game with, with 16 kills and 0 deaths, as the second highest-scorer on the server.
1) They don't have 'paper-thin' armor, I don't know where you're getting this. It takes MANY passes with a Sulla Prime to bring one down. With some 'advanced' maneuvering and passive sensors (basically just fly like you're drunk) they'll eventually give up or lose you. I did manage to down an enemy Hawkmoth with my LRMs, though it did take three shots to do it.
2) Lag shield + ultra maneuverability. Aircraft can take 15G turns like it's nothing, which doesn't help. The fact is, 2-3 seconds of concentrated AC fire on an unmoving Hawkmoth located 5m away might tear it up, but at 600-1000m, you're only going to land a small fraction of that fire, giving them plenty of time to lock onto you, throw some missiles their way, and lazily float home.
Every time I get in a VTOL I feel like Zeus floating around in the heavens throwing lightning bolts and whomever displeases me. There's literally no skill involved in this at all, no sense of danger, and I never feel like I'm even part of the game. I just vacuum up points for doing nothing.
Kingleer's probably got more hours in the Hawkmoth than you guys have in the game, so I take whatever he says for VTOLs to be an expert opinion.
The same way a guy who really loves Rogues in World of Warcraft probably isn't the guy to go to for a neutral opinion on them...
Flying aircraft in this game doesn't have the same sense of participation mechs or vehicles do. It's easy as you're rarely in danger, your weapons require next to no skill to use, and they all do hideous amounts of damage. Even if you do get shot down it's not really a big deal - they're cheap, fast, and you're back in the fight in no-time. When I get killed in my Mk2, it's a bummer because I have to dedicate 3 minutes to lumbering across the battlefield (if I can even afford another one). When I'm in my aircraft and someone DOES start harassing me, I just lazily drift somewhere behind a hill - or maybe just go bug out and let the base turrets handle them - with a 1km range it's pretty easy to avoid conflict. When I'm in a mech and I find myself in trouble, I have to fight tooth and nail with everything I have and there's an awesome feeling when you crawl out of the fray intact.
The only way it's possible to really shut down even just one or two aircraft is to erect a
disproportional defense against them. It's downright bad design to require an uneven ratio of players as a 'counter' to something (meaning it takes 2 players to counter 1 enemy, or worse).
