This is not CSGO. You are not looking at 5 dots on the minimap.
Ok, and? Your point is?
The entire UI of health bars and capture points must is the priority over the "green" color assignment. The POV player's color must always be the same.
That is your personal opinion, and it's based only on prior titles in this series. Anyone with color vision and a working short term memory should be able to identify the color of their units and remember it while playing the game. There is no RTS law which states that: "the player's units must be blue!!"
This is why people have nicknames, so I can say "dono help me", and if the mental capacity of the average player isn't enough to read couple letters, then it is definitely not enough to always re-color the UI every round.
I see no reason that they can't have nicknames and unique colors. This is, again, an argument from your personal opinion.
There might be some intermediate solution where another detail/attribute is assigned to work as the "green" callout, but it is at the bottom of the priority list.
My man, I don't know if you realize this, but unique colors are already implemented in the game. You're the one advocating for the intermediate solution here. The devs have already made their intention clear that they're going to assign unique colors to the players. Whatever extra detail you want to add is what's at the bottom of the priority list.
+ there is ping that isn't in CSGO. I can click on your unit (with a functional ping system), and it will send you a command to attack or retreat or careful. No need to even engage in the text or voice coms.
Ok, and? What's your point? Csgo also has a voice chat. I don't know if you play with other players or not, but a ping is not half as effective in getting someone's attention as saying their name (or color, in the case of csgo and now coh 3) is.
I've already stated that I don't agree with assigning teammates red, pink, orange colors, etc. Are you really here to argue with me that players being assigned *actually* unique colors for the first time in the series is a bad thing? Don't bother, because you're not going to convince me.
