Without the ability to sim, GW is simply too long to complete daily (at least, for someone like me who has a job/family). Please half the nodes, tweak the difficulty, increase the rewards.
You are lucky @MuggerPrime. You only have to compleet it an set amount of times (100 complete right?) and know you will be able to sime whole GW. Think I did about 10k GW's battles (over 800 complete GW's) without able to sim them.
