Once you've got a few hours under your belt you learn what enemies to avoid for your current build, e.g. if you're a frail summoner you want to avoid enemies that use the Zap skill since it chains between units.
Though no matter what there are two sections where you don't have a choice in the matter. Pic related where my build to sack summons went against these fucks who hit me for 30k damage with 100% accuracy which bypasses 90% of armour and block.
