Having spent a day solidly playing it (as well as other times playing it, but this is my only "extended" time playing it) I can categorically tell that it is broken. Why?
The striker class, ruins the entire game. Simply put, it is overpowered. They can move across the large maps in a matter of seconds. atop of this they can re-heal faster than any other class. there current lower health de-buff, does nothing. the only counter that they have are guns, which are low damage weapons and easy to dodge with extra speed. this means that the class has no counter. (Guardian has high damage weapons as a counter, and the recon has bombs as a counter).
Atop of this, the player balance is ruined. the game is often controlled by one good person, of whom causes the entire game to be steam rolled in their favour.
Ping differences ruins the game. I've had it where i've been a considerable distance away from the player, and damage was taken. Or more commonly, I have my shield up, and damage still goes through it.
Trinket loadouts make an unbalanced game even more unbalanced, yano, a striker with a penta heart trinket? removing its one weakness.
SIMPLE SOLUTIONS TO THESE PROBLEMS:
1) Class limits to all classes
2) give the striker a boost cool down, akin to being stunned for a few seconds. they cannot boost in this time.
3) A players "rank" should be averaged from their damage, Caps and Defenses.
4) teams should have a roughly equal "rank points"
5) if a game has been steam rolled, then the highest ranked player from that match should be swapped with the lowest ranked player of that match, at least.
6) better ping prediction
7) just remove frostbite, everyone hates it
8) Trinkets have no effect on the user, players limited to their first two weapons. UVs are ignored. this will add an element of skill and choice of loadouts instead of "LOLIHAVEALLTHEUVS. IMINVINCIBLE"
Each class fills it's role.
Striker is offensive
Guardian is defensive
Recon is supportive and offensive and defensive.
I've played more LD than most people in the game.
The only thing that needs fixing is guardians asi needs to be cut a lot.
