1) Larger scale - Increase player count, large maps
(raindance size), with strategic points of interest
instead of repetitive empty hills.
Points such as big hills where its of strategic value
to get a hold off, if it to put a spawn beacon on
for closer offense spawning or for chasers.
Points where you  can cut off back routes,
place radars on, w/e. With larger scale the the game
 can be played out differently every time, open up
more strategy (instead of the current, strategy
which differs mostly by class selection).
And with larger scale individual skill matters
 less than the teams  as a whole.

2) Teamwork - viop for easier communication
minimap/radar so they know where their friend are
, more vgs for those who don't speak the regions
language or don't have a Mic and command
markers/map for leadership and organization.
Encourage teamwork, don't frustrate
them with not giving them proper tools to
coordinate simple things. Or make them find
a 3rd party software and servers which not everyone's on. Give more accolades for team centric actions,
clearing the stand, killing sniper just in time,
escorting, etc... give them badges for it to.

3) Tutorial - a mandatory one which teach basic
     stuff (sking, air control, energy management      shooting ground targets with discs, mortar, sniper
  , taking out base assets, clearing the stand, roles,
classes, how to decloack an inf, inheritance, capping).
And more Advanced ones such as blueplates,
leading, chasing bots, advanced energy managements (jumping fast through high loops), flag play (passing,
defending a dropped flag, timed return), escorting.
Reward them with xp, unlocks, perks...
