I agree with your want list 100%.
Unfortunately, these are all very doubtful. I know the day after there will be topics about "Brink 2," you're always going to have some people infringing on the rights of other, DLC will probably be paid for (at least on consoles) and if a nerf is implemented, it will probably make the ability/weapons next to useless. I'm a cynic.
Well,it's not that i mind if when release of Brink and same day a Brink 2 thread will appear,i just think that we should enjoy the game atm and start discussing about a game that will come up (if) after a year.I mean if we want a creative discussion we can start a discussion about what is bothering us/bugs etc and what improvements we have on them and after a month,i'd say 2,we start throwing ideas about what we want in DLC.
I just find it meaningless start Brink 2 discussions after an hour of Brink release.I'm not judging negative here.
