So how are you defending vs projectiles/archers?

At the moment 95% of my deaths comes from archers (especially in scourages, at 100+ stacks these things are super deadly, even white archers just hits for 5k+ damage).

What are your ways to mitigate this? We used to be able to block projectile attacks, but not anymore (mod from rare shields is removed). Super high evasion? (even on character like templar?).

projectiles are either attacks or spells, so u can block them the same as always.
U just can't have more projectile than melee block through that shield affix anymore. (they buffed general +%block on shield affix tho)

Also evasion obviously works against projectile attacks, as does Spell suppression/dodge against spell projectiles.

Flesh and Stone gives you additional damage reduction for ranged attacks, that come from enemies that are not nearby.

The best defense against projectiles will always be to manually dodge them, so you wont get hit at all.
