So say something is attacking me with blue this is what happens:
+10 Dizzy (Attack)
+5 Damage (Attack)
My stats end up as:
10 Dizzy (Attack)
95/100 HP (My HP)
So I defend and they attack again:
-10 Dizzy (Defense)
+10 Dizzy (Attack)
+5 Damage (Attack)
And my stats:
90/100 HP (My HP)
+10 Dizzy
Well what the hell did defending just do for me? I could have attacked and dealt them damage but instead we just ended up where we started and now I have more damage on me. Yes these are imaginary stats but for the most part it seems like it's never worth defending as you might as well just pound out attacks.
