Andor's Trail

Ok this is my set up as of now.

LV 22 EXP 183718 HP 58 AP 11/3 AC 138% AD 19-31
CH-10 (negative) BC 104% DR 5
Helm-Crude Iron Helm Neck-Necklace of the protector
Armor-Stone Cuirass Weapon-Balanced Steel Sword
Shield-Wooden Defender Rings-Ring of the Protector x2
Boots-Vacors Gloves-Heavy Plated Gloves
Skills Bark Skin 1 Combat Speed 1 Increased Fortitude 2
Regeneration 1
Now my problem started when I decided to put my final skill point in Combat Speed it made my AP 11 so when I attack 4 AP BSS (Stone Cuirass gives a debuff of plus 2 to ap) now its 6AP. 11-6 is 5AP left and now the turn wont reset because there is still 5AP left. I receive a message saying not enough AP left this round. I understand and accept the penalty of the armor but it is a huge huge hassle having to hit end turn while grinding. Is this a bug or is it designed this way?

With 5AP you can try to flee or use an item. You don't want to be deprived of such a possibility do you? The game only ends your turn automatically when there's nothing you can do with the AP you have left.

Your right I wouldn't want to be deprived of the option unless i want to attack again.
