Expanded Arsenal stacking

[SimpleFish5655]

Is your feature request related to a problem? Please describe. I'm frustrated when the game seems to punish going into a spell focus of a Wizard's main school. Scenario as follows:

• Nenio has a spell focus of Illusion at level 1
• The description of the Expanded Arsenal mythic feat states that "Select one school of magic. All bonuses from your feats and mythic feats that apply to another school of magic, such as Spell Focus feat and School Specialization mythic feat, now apply to the chosen school of magic too."
• However, Expanded Arsenal only stacks if you do not have a spell focus in that school. I believe you can stack up to +14 DC from the other 7 schools if you avoid spell focus on your main school and just take the expanded arsenal. Taking a spell focus in main school basically is suboptimal in every scenario with expanded arsenal.

• If I want to build Nenio with high spell DCs in Phantasmal Killer / Weird, her spell focus in illusion is a poor choice in the current game's implementation of the mythic feat

Describe the solution you'd like Could Expanded Arsenal be made to work if you had spell focus on your main school, per the mythic feat wording?

So... I do what to fix this, BUT not in a way you'll like. Stacking multiple schools is not intended behavior as far as I am concerned and stacking will be removed.

Would you allow stacking only 1 school? e.g. stack SF / GSF Evocation onto SF / GSF Illusion using expanded arsenal for a total of +4?

Or is your intent that Expanded Arsenal should just act like it gives the benefit of SF / GSF to another school which you have not taken any feats in?

You're looking at Expanded Arsenal incorrectly; you would want to be putting Spell Focus and Greater Spell Focus into a single school, your primary one, and then use it to make it so other schools get your specialization/focus.
