With the most recent patch, we saw the number of unsatisfying and poorly performing supports increase rather than decrease. Unfortunately, this seems to be a trend, as supports seem to only have gotten worse with each patch.
Therefore I think it would be useful to make a list of all the supports that aren't really up to snuff, why they feel unsatisfying and what would make them better/useful again.
1. Helicopters: Not a round goes by when I don't see one or both of these get shot down by bots, often within seconds of arriving. As things stand, helicopters seem like a trivial threat to bots and a substantial threat to the players; while players are still forced into cover, the bots just blow the things right out of the sky
The worst part of this is that the helicopters were actually pretty good till a little while ago, when they acted like genuinely powerful but limited support and justified their one time only use by actually being powerful and not a massive gamble.
Ideally, a helicopter getting shot down, especially by bots, should be an extremely rare occurrence instead of the guaranteed one that it currently is. It's okay to see this occasionally, say once in a dozen matches, but any more and it just makes the support unstasfying and too much of a gamble.
2. Explosive Drone: This one has been nigh on useless since the beginning. It's gotten to the point where you don't even consider calling it in, since there's only 2 outcomes that you'll ever see; either it gets shot down or it glitches/gets stuck and never reaches the target.
I think that a simple solution would be to make it swoop down from up top (thus avoiding the many obstacles that it inevitably gets stuck on) and attack as a guided bomb (descending from a high altitude, guiding itself to the biggest target/largest enemy concentration, and exploding) instead of meandering in at a low altitude.
3. Poison Gas: The only somewhat useful one of the lot. The problem with this is that it doesn't really permeate the area it does hit, and even when it does, it's area of effect and duration leave much to be desired.
Make the gas permeate the area it hits and make it spread much further out.
4. Rocket Barrages: A somewhat infrequent, but very annoying bug seems to occur, where every so often, the rocket barrage just doesn't show up. No idea whether it doesn't spawn, or just explodes somewhere uselessly; but the bug is extremely annoying.
