The monsters are not well designed. The AI is too easy. Monster attack animation delay is too long. No class is weak to any types of mob. No strategy is needed to defeat mobs.
All of this results in - no need for party play, hence repetitive and boring.
While this might improve in higher levels, I’m already at rank 4 and it’s not any more difficult. I’ve also read high leveled people say that lvl 10 is the same as lvl 100 is the same as lvl 280.
IMC please tweak the monster AI so they don’t take 3 seconds to react to being attacked. and take 2 seconds to attempt a basic attack. It makes the monster look absolutely stupid and pointless.
