there has been no confirmation whether it is intended or is a bug. but as of right now ranger is worth it, and if you drop ranger you drop rogue. alternative here would be archer 3 scout 3 musket/cannon i think.
sapper 2 scout 3 takes a dedicated party. but, linker and cryo aoe support with your broom trap and flare shot are decent, while chrono keeps your aoe burst going more often. for sustained damage you spam split arrow between multishots. its aoe is reliant on others, but the r7 falcon route is the opposite, it provides more aoe capability to the others in your party.
i would say these 2 builds are even in their own role for your consideration, but your archer aoe/aoesupport competition for groups does your job with more sustained damage – sapper 2 wugu 2 cannon beats sapper 2 scout 3 by my guess, and the falcon path for scout 3 has to compete with other falconer builds (qs3 musket/cannon) who do far more 1 target than you and actually do damage in a mobile mob situation. if i had to give an opinion on which of these 2 is better, its the sapper 2 scout 3 as long as your immobile damage fits into the group situation.
however, i back dream’s build as top scout 3 that i know of with the cannon/musket at r7 close 2nd. the 2 alternatives here are a step or two down.
