Very unfortunate indeed. They really should fix the bugs before screwing around with gameplay and weapons as I find myself playing significantly less by the day. Played every Battlefield from BF2 until now and this is the first time I'm actually considering not buying the next installment. I've seen plenty of software trainwrecks in my line of work but as far as games go, this takes the cake for the past 18 years at least. Also fix the server code for instance because the only possible reason I can imagine for throwing all players off the server after one map is because you are unable to keep it running for longer (memory leaks? handle leaks? deadlocks?). Not fixing this is one of the primary reasons players are giving up because it makes it appear that just a handful of players are waiting in queue for most of the time. Stop tweaking freaking tanks and guns until you FIX THE BUGS. If you don't you're all but guaranteed to kill the franchise.
