Effective and Ignore Resists?

[phaolo]

Guys, can you check this thread? (starting from my first post, not the OP)

IGNORE Resist or Weaken?

So: weaken --> PvE and PvP, %chance for -50% enemy res (correct?) ignore res --> only PvE, means always 0 enemy res (right?) ignore res + weaken --> weaken is wasted, unless you use the same character for both PvE and PvP? What about the “effective” mythic? (on dmg, changes element to the enemy’s usual weakness) how much % is such weakness? “usual” means that it could be wrong for special monsters or players? it seems useful with weaken, but wasted with ignore res…

Maybe I’m stupid or I can’t explain myself, but I still don’t understand how Effective,weakness,resists work when calculating final damage to a monster
