You running a level, approach mob entered a room, push "attack" button and.. nothing.. Toon shaked and a line appearing to chest in previous room. Wrong target acquired.. Mob shoting you and you can do nothing, you cannot attack him.
To Acquire him manually you need to tap him! But two conditions:
1.You are moving and mob also moving. It's deadly hard to target him
2.To target him you must not tap him simply but to tap some place below his feet.

What we need is
1.to make "smart" auto acquisition of targets ahead of the toon, not behind
2.In case distance to target too far and closer targets are available - re-target again
3."Crazy" targets which cannot be killed because probably too far from main position - line to them should disappear automatically
