I'm sure most of us are aware of the changes by now, and most feel that GW is harder unless you have deep pockets, but this is not the case. Because by using the new retreat, you can get your matches to all be like this.http://imgur.com/aFhO8Um
All my heals were on cooldown from the previous fight so I had to get through this match taking as little dmg as possible, using the new "retreat" I manipulated RNG by retreating a few times till it heavily favoured me and gave me such results. Match ended with my guys fully healed and off cooldown.
Everytime you retreat and reenter you can keep changing the outcome of RNG as long as either you change a party member or change your first action. But you actually don't need to change your team, only the order in the team. You could swap members 2 and 3 with each other and that's apparently enough of a change to get a completely new outcome.
Also only the first attack needs to change for the entire match to go differently, if Daka went second and missed her stun, as long as Dooku preformed a new action, Dakas stun can land on the same target it previously missed
Now GW is easy beyond belief as long as you don't mind spending time on each match getting RNG to assist you. The previous retreat still allowed for strategy even if you could get rid of debuffs, now it's just trail and error.
