Do not train speed and agility when they are in the 70's, that is a complete waste. Also, 73 is the cap not 72. My advice:
- Speed to 73, you have passed the point where a blitzer archetype is actually going to be realized. Speed should have been taken to 77/81 then followed by agility. Way too soon to be capping str/tack, also no more SA's.
- vision to 60 while you're training agility.
- Once agility is about 33, start adding sp's to it and bring it up to at least 68, ideally 73.
That should keep you busy for a few seasons.
