How is it too hard with those 2 abilities? They're woven between 3 second GCD abilities that are on a 40 second timer with 2 stacks. So you do Dreadwinder > Hunter's Coil > weave in Twinfang/blood > Swiftskin Coil > weave in Twinfang/blood again. Not that hard.

I think they overdid it with combining so many abilities in so few buttons with, and the flank/hind abilities seem a bit redundant, but Viper feels easier than Reaper so far.
