This seems to always be a subject in team based shooters. There are many schools of thought on this and would imagine anyway SD goes someone might be disappointed.
I personally don’t mind arrow indicators liked we used in Q3F/ETF. I can see how some might not like this though as they feel it takes away from the skill and realism of the game. I would love to see arrows but at the same time I would like an option added server side to have them removed for a hardcore mode if you will.
This then does bring up another issue if it’s server side controlled you run the risk have bloating the server side settings and how to properly indicate to the player which settings are enabled. You might be able to eliminate that with group settings that can be easily indicated. The group settings could be classified with level of difficulty where normal is everything on like Player Indicators, Crosshairs, FF Off, … & hardcore would be something like no player indicators, FF On, No Crosshairs, … & maybe variants in between the two mentioned. You could run this risk of server fragmentation though so it’s a design decision that would need to be discussed in great detail.
Edit: Just thought of something else. If some servers have these settings on and some don’t does that impact the server stats? Would players feel that players playing with indicators should gain points in their stats at a lower pace because of the skill level has been lowered?
