I own both BF2 and BC2 and I hated the weapon unlock systems they had mainly because they took forever to accomplish. BF:BC2 isn't as bad as BF2 when it comes to how long it takes, but I certainly wouldn't relate BC2 to RO2.
For starters, in BC2, most of the classes don't have their main weapons or equipment available from the start. Medics don't get medkits or paddles, Assault doesn't get ammo packs, Engineers don't get the repair tool or AT mines, or decent rocket launchers and the recon doesn't get mortars, or motion sensors, etc.
And to add on top of all the above, BC2 gives higher leveled players body armour, armour protection for vehicles, magnum rounds, etc. which makes it even harder for new players to take them out, while they can use body armour to take more hits and use magnum rounds to take you out with less.
In RO2, you don't get extra body armour or special ammo, you get additional weapons or different ammo mags, but no weapon suddenly becomes more superior over another.... one round in the chest or head with any weapon and you die..... so trying to grind to unlock these features isn't as important as it is in other games such as BC2 where if you don't grind, you're stuck at a disadvantage.
I'm looking forward to it in RO2.
Okay, so unlocks in RO2 dosen't give you the same kind of advantage as in BC2. A level 50 player still dies from one shot to the chest and so on.
But we still have weapon unlocks. Weapons that perform alot better then the weapons we start off with. Mp44 for an example, rifle and sub-machine gun combined. If it is anything like it's real life counter part that gun will dominate in all situations. Another one is the semi-automatic sniper rifle.
Then we have all the extra unlocks. Bigger clips, scopes, silencers (?). So for me, it still looks like higher level players will have a big advantage, even if they die by one or two shots like the rest of us grunts
Say if you have the mp44 unlocked, why ever bother using the mp40 again? In RO1 this worked out perfectly thanks to the class restrictions. Rare weapons was rare. Okay, I guess it all depends on what classes gets access to the mp44, but if it's available for say; the squad leader and the assault. Then I have a hard time seeing why anyone under level 50 (guessing here) will ever be using the mp40 again.
So my worries here are that exotic weapons will be plentyfull thanks to the unlocks and that new players will have a hard time staying alive thanks to this.
This might force new players into the grinding state.
