Giving everything the same priority is a terrible idea.
What if you have a single shrek squad? In the current system the dude with the shrek will fire at tanks while the 3 rifles will fire at infantry. If everything had the same priority the entire squad must fire at a tank or infantry, which is stupid.
Holy fuck, you can read even less than the other guy. Kudos to you.
I think you really need to learn to read.
You suggest changing the target priority for everything to 60.
Which means a gren squad with a single shrek would be forced to fire on
either a tank or an infantry squad, not both, as it can currently do.
Flame less, learn to read more.
