Can you make it so when you are in mass fights/team fights that the target system makes you prioritises enemy ninjas first instead of always targetting your own villagers/org members when you are close too them in group fights.
I like this idea but maybe instead of this make it a toggleable button that can assigned to whatever hotkey sort of like the walk/run toggle.
Overall on the subject I believe this is something that all players would enjoy if they realize it or not.
A good example would be any MMO are you able to tab target your allies while targeting through mobs? I can't think of one where you can haha. Usually to target group members you would use the party window but when you're deep in a large scale fight you don't have the time to take pressing X over and over between ally and enemy. Making it target just enemies wouldn't raise or lower a skill gap either so I don't believe that's really an argument on why we don't need it. But it would be a great QoL that I believe every ninja would enjoy.
Regarding to the post overall wonderful suggestion I hope we see something done about it!
I think something like this would be great to have, Although wouldn't use Alt + since that's for Self targeting. instead I would suggest the following.
X = Enemy/Mob Target
Alt + X = Self Target
CTRL + X = Ally Target
I'd say there's a difference between making something easier, and improving QOL/quality of gameplay fluidity.
This, I'd say, counts as the latter. Other games have this feature as well.
