I would say BF took the easy way… make the differences small enough that they aren’t a big deal.
The hard way is to do it like AVP
From the available info, it looks like et:qw is going to be somewhere in between.[/quote]
agreed. BF2 isn’t asymmetrical by any stretch of the imagination. The differences are so minute that you don’t need to adjust any tactics to account for the differences.
I think that the “classes” are similar enough with the “roles” unique enough that it keeps things different - yet balanced.
For instance, a medic can go in and “revivie” players on the field which keeps the front line moving if the medic is good. However, the stroggs have to create new spawns off of the same dead soldiers which can add a simple twist to the tactical usage - and interesting battles over those same dead bodies. Since Stroggs have to kill a GDF player to create a new spawn, they need to be used in conjunction with someone/thing that can kill the enemy for them to be able use the corpse spawn. A medic just has to be near a fallen soldier, perhaps with some cover (not that I am saying its an easy task).
same with the weapons, each will have anti vehicle and anti infantry style weapons, but they will function differently. Its not just rock paper scissors with everyone having the same rock, paper and scissors. its completely different which makes it more tactically compelling to me.
