LOTS of questions with Draconic Exemplar (Rite Publishing)

I just fell in love with this class. I love it. Point is, the "Grow in Size" Bonuses and Nerfs give me headache. My doubts are:

1. Do I still have to apply the NORMAL size rules? Because if that were the case, the Strength gain would lose meaning due to the Attack Rolls penalties, and the loss of AC, together with the -10 you get in Dexterity, DESTROYS YOUR Class Armor. Sure, you have an absurd amount of CMD and CMB, but it's not exactly a good trade

2. How should I handle natural attacks if I have such a reach? I know that maybe for those who follow the rules to the bitter end it can be stupid, but with a claw from a 4 meter arm shouldn't I be hitting a lot of enemies and also risk to hit my allies? It doesn't make sense that I can only hit 1 enemy when I'm huge, nor that my allies risk nothing.

3. Ok. I'm Colossal. Long or Large?

1. Your ability scores change as listed. You do get the size penalties to Attack and AC, with the size bonuses to CMB and CMD. You do not get additional changes to Strength or Dexterity with the size change. While your attack bonus doesn't end up changing (Strength increase, Attack decrease), your damage increases both in dice and in static bonus. Your Touch AC will be very low, but all giant creatures suffer bad Touch ACs. With Natural Armor increases, you regular AC and Flat-Footed AC should still be good.

2. Your natural weapons do not become multi-target or area of effect attacks. You still only attack one target per attack. That would also be the case if you decided to wield a manufactured weapon.

3. At colossal, you would take up 5 squares by 5 squares on the map and have a 5 square reach (6 with bite iirc). Long versus Tall doesn't really matter.
