Do you think going SA3 for max broom is worth it? It seems to be our best trap.
No it does not hit fliers.
And I’m speaking in regards to the sapper class design as a whole, as in, just because 1 skill is useful, doesn’t mean the class is in a good spot.
Currently Sapper 3 is heavily recommended against due to overall usefulness of the class.
Basically you only go sapper 3 atm if you are prepared to have an underwhelming character because you love the concept of a trapper, and pray to IMC for rework/buffs atm.
