I've done more capes than anyone here other than the Chinese gold farmers, which is a full on group. Fact of the matter is you can't tank a 360/180/90 wave very well so calculating all the spawns and moving around appropriately only does so much. You could get 2 hit no problem by the 180s.. and the 90s will hit constant 8-12s
If for example, I had a 360/180/90 wave, and the 180 and 90 were in the NW corner, while I'm north of italy and the lvl 360 is south or middle I have to do the following
- tank around the 180 and 90 to get past the 360 and separate it from the ranger
- Pray melee and kill the lvl 90.
If anyone can do it I can, but it's going to be a 3+ hour process and pretty stressful. All for you to take all the credit afterwards and get annoyed if someone fails? That doesn't sound fair to me. I've done capes with 50 range before and it's not easy. Your expectations don't match the reality that any bad spawn is gambling a quick KO.... sweets don't heal fast and your range is so low you can't afford to bring many brews.
I'm not going to lie to you by guaranteeing success on a cape that I'm not comfortable doing. You're asking something that only a few people in the community can do, last I recalled they weren't on this forum either.
