Well... i only partially agree with 6thAB here.
The solution to glider crash abuse is, in my opinion, the best you could find: you can still drop your commandos behind enemy lines, and i think it still preserves the capability of removing mgs and mortars since your opponent can move them, preventing (early game) heavy losses in resources invested to get theese units, but not relocate and set up them quickly enough to harm your freshly dropped squad, and the same thing applies to AT towed guns.
"Good" thing is green smoke might still not be noticed by your opponent if properly distracted, letting you "abuse" glider as usual.
Problems come when you're trying to attack a position with infantry squads: after seing the smoke they can easily relocate behind a green cover so to have a huge advantage against glided commandos.
All theese aspects are new downsides for the glider user, but have, from my point of view, made this game feature more realistic: i think gliders were sent behind enemy lines during the night to prevent them from being seen, but if a glider landed somewhere in enemy territory during the day, it would have probably been spotted and units would have taken counter measures (even tho daylight fighting is a map limitation itself).
What i agree with AB on is that early gliders+commandos are now underperforming or, at least, much less worth it: this doctrine is very versatile, but a huge part of its tech tree is focused on infantry upgrades, costing 13 Command Points (not counting the booty traps one which does not directly affect combat capabilities) to fully upgrade your infantry, remembering that 4 of theese 13 command points are just dedicated to glider upgrades, making the tiering-up exceptionally slow. Add the fact you might need some command points to unlock airstrikes and this becomes even slower, delaying the combat effectiveness of commandos to a point of the game when they have to face already veted infantry which, in the case of sten commandos, can easily outrange and kill them. When fully upgraded they can stand enemy infantry in an amazing way, even thanks the the 2 vets they get with unlocks, but, as AB says, this change made their life much harder in the early stages of the game, consistently reducing the possibility of leading operations behind enemy lines ( going straight for SAS to do this is not really an option at the moment since, as sten commandos, they would completely die to the first units sent, or just relocated, to counter their no more sneaky drop).
Personally I didn't have a hard time adapting to this: i just stopped sending glider on enemies (except for rare cases) and substituted it with 95mm cromwell while you produce infantry in the back. You see an mg? You bomb it with cromwell yeeee!! You see a mortar? You bomb it with cromwell yeeeee!! You see some naughty weeds on the field? You bomb it with cromwell yeeeee!! So much fun yeeeeeee!!
I hate the indirect fire solution because it often ruins strategy and challenging gameplay (and pissing off players so much), i thought many times to ask the 95mm cromwell to be removed form RAF doc or, at least, to require it being unlocked from the tech tree, since it makes it too everything-capable and less specialized, but i think it's now very necessary.
Other aspect i think this change has made it harder for CW player is the delay to combat engeneers glider: while commandos have Ab type and longer sprint unlock, which makes them a little harder to hit while closing distance to get in range, sten engies are much harder, once they're not dropped right into the action they really become insanely hard to use. If dropped into the fight they can wipe out entirely even a gebirsjaeger squad, making the best use of stens and flamethrower, but when you're trying to attack with them, flamethrower is just 1 less man shooting while closing the distance, and once they get in range they might already be too few to fight properly.
I'm not yet suggesting changes to this new mechanic, and i probably won't, i'll just try to adapt, but in this case I'm just a little disappointed by devs for not making the announcement here on forum (i'm not using facebook) and have a quick discussion about it before the effective change to consider every aspect even if they already decided this (as i said, i'm still of the idea this is a good solution).
