F Shieldbearers

Whoever designed that monster and decided to put them in every zone from level 2 is a monster. It is a nightmare for any attack build and anyone playing HC or anything beyond SC and even in SC it's annoying beyond end. First why can it block attacks when you so early can basically not do anything about it. Why do they maim you so you basically cannot get away from them early in the campaign. They have more health than other monsters at their level on top of that. You can only pray they don't spawn as a rare monster or blue pack. Why is this in the game in endgame it doesn't matter because you oneshot everything anyway but early it's such an unfair monster with so much stacked against the player while you as the player have no tools to deal with that because it's the freakin rhoa zone. Why? Why? Initially this was just annoying but now deep into the league after playing Gauntlet and some more modes it's so annoying.

Considering I have no idea what a shield bearer is, or any memory of having issues with any specific non-unique monster in campaign (outside gauntlet), this seems like an overreaction.

I'm guessing OP means Afarud Shieldbearers, a monster type that is part of mirage spawns.

Shieldbearer is the mirage monster with the shield that maims you and goes poke poke poke until you are dead while leveling.
