You clearly do not understand the game mechanics or the different character kits.
* GP is a measure of resource investment, not combat power
* There are a lot of different Bounty Hunters; which ones you use and how you use them is important
* Some squads effectively hard counter others because of their respective kits e.g. Darth Revan squads hard counter Jedi Knight Revan
* Some squads require specific counters e.g. you can't just throw any old squad at Geonosians but certain squads counter them easily and certain characters can solo or duo them if the conditions are right
