Removing units from battle by clicking them.
This is really not fun to watch how unit with 0.00000000000000000000000000000001% durability trying to destroy wall and blocks all units in line.

But lvl1 unit and unit with 0.000000000000001% of durability its not a same thing :) Yoy can avoid it only by using unit with 1,5 range in first lane, unith with 2,5 range in second line, and flying unit in third line, or with air units which dont stop, or with perfect calculations.
