I play as a healer and has done that in many mmorpgs previously and the one single feature I miss in New World so far is the lack of ability to use the keyboard to target group members. So my suggestion is the following:
Implement the option to assign a key to target each team member, for example shift+1, shift+2, or F1, F2 etc with one key assignment representing each team member.
The wheel assignment that we have today is extremely inefficient and very annoying.
