What do I like -
The change to classes and change to the damage done by rockets means vehicles are more fearsome to general infantry but more vulnerable to engineers - this is very good.
No longer being shot at by 10 rockets at once which each do a small amount of damage.
Turret speed increases seem to be good in general now.
Weapons / gadgets for more than two seats - ie the MAV, tanks and so forth. In previous games only a couple of vehicles had weapons and gadgets for the third and fourth seat.
In BF2042 the players in 3rd, 4th, 5th seat and so on have weapons and gadgets available - this has been the case since BF2042 came out, but its one of the best inclusions especially with 128 players.
What do I dislike -
Jets can bounce off so much stuff before exploding.
So many vehicles in the Nopats category - I wish there were more vehicles to differentiate US / RU.
No water vehicles apart from on portal maps - some of the existing maps could easily have RIB and jetskis implemented, especially for getting to flags at the start of the map.
No specific anti tank / bomber aircraft - ie A10 / SU25 in previous games.
I wish there was a transport vehicle other than the LCAA and LTAV4 which was slower but provided more protection - ie the MRAP / SPM-3 or HMMWV / Vodnik. These could also have unlocks differentiate from the other transports - like an AA missile turret. I know we already have the EBLC RAM, but I'm think of less of an attack / scout armoured vehicle, and more of just a general transport vehicle that you aren't a sitting duck in (in the transport rather than armoured vehicle category).
I wish the Wildcat gun had a higher max firing angle - I know this has to be balanced so air vehicles aren't totally dominated.
I find the kinetic grenade pods sometimes work like a treat and at other times just don't work.
There needs to be more infantry Anti-air weapons / gadgets, preferably things that other classes can use or the engineer can deploy and other classes can then use - AA mines, deployable AA manpad, grenade launcher AA proximity round, AA proximity for unguided rocket launcher - ie AA version of Recoilless M5 (engi only).
What I would change -
Add more vehicle types
Add some more unlockables such as -
-togglable IR / thermal sight (set up not to take up weapon / gadget slot)
-reactive armour
-ammo box / loadout crate / medic drops for transport vehicles
-something like a soflam for the 2nd seat in the Nightbird,
-More unlocks for gunner seats secondary weapon - wire guided missile option for gunner seats Apache / KA-52,
-Mine layer
I know this will never happen but I wish a fast roping ability was added to transport helicopters (including portal ones), I've wanted fast roping from helicopters in Battlefield since the initial BF2 trailer. It would be basically pointless given the parachutes, but if there was an option to turn off parachutes in portal / select which classes & pilots get them then this would be awesome for setting up more milsim style servers.
