Finisher cost question

how much AG would people suggest shooting for when creating their finishers?

It depends. I have a very high AG (950) to be able to hit my finisher as early in the match as I can. It costs 10,000 adrenaline to use. It might seem high, but it is frankly not too much for your final finisher. My advice is to max out the damage first (higher end at 99,999) and then to raise the attack bonus. You could probably use a finisher with a cost of 1,000 adrenaline for now.

I'm still using my original finishers (it's actually something I've been looking to change, but the only things I've ever reset on Semag are ATs and matches thus far), which require 807, 700, and 330 adrenaline (330 was my very first finisher). My AG is also only 146.

I think the "standard" out there for finishers is for the adrenaline use to be 30xAG. Most people alter their finishers as they go, making them stronger as they level.

You need to stockpile the TPs and do a move reset if you have never done it. Then you reassign your skill points and buy back your moves and you have a ton of money to put into entrances. It's the best way to gain more experience.
