Sorry 'bout that toad.
Let me take a crack at your questions..
Low-Alt buffs...were here before, but much more prevalent after change to bombing. (Add in dive bombing buffs, as well)
Frankly, I find this group laughable. They provide easy fodder and rarely if ever hit anything of value. 90% of the times I've seen these types come into a contested area, they don't make it to target, much less hit it. I believe this group is negligible.
Suicide jabos have become much more prevalent but they've been here so long, I can't recall when they really got out of hand.
I just can't see, though, how making the capture more difficult will increase suicide jabos. They will really be useless.
If you're serious about eliminating them, you need to impliment several ideas from this thread. (Don't worry, none of them were mine).
Add perks to mid and late war rides.
Add perks to Jabo bombs.
Add to size of town at field
Add mannable or AI ack
Increase fuel bunkers by 50%
I honestly cannot see how watering down the game will help those with little skill, or regard for survival will suddenly develop skill, or learn to move up to the next level. I can only think of ways to try and prevent these people from succeeding, and thereby frustrate them. I'm not very good at figuring out how to inspire these people to change their gameplay.
