First, please pardon if what I am about to say sounds like rambling ( probably will be anyways!:) )
Miska...your "no icons" argument is very valid, it would "immerse" the player into a somewhat "more real" environment, but not completely. Going off what Lowe stated, I think it would make the game extremely unenjoyable to the majority of players in the CT, and our numbers would be lower than what they are now.
Another point...the visual acuity required to see and Identify a contact before entering the merge is just not possible with today's video card/ monitor technology. Shape breakout, let alone color breakout, and depth perception are just not there. Without the aid of GCI, people would wind up going from one friendly group to another and quit from the frustration of never finding the "fight".
I think wanting to make tthe CT more realistic is truly admirable, but I feel "no icons" is not the way to go. How about turning on friendly collisions?? That would definitely make furballing more realistic
Well, just my 2 cents worth
