I think that sometimes designers will design a monster that's numerically in line with Quake monsters, but put one in a test box with a pillar in the middle, easily kill it without being hurt, and think "oh, I need to make that way harder." Thing is, every existing Quake monster fails that test too. You can even (laboriously, with practice) solo a Shambler with the axe just by doing the "shambler dance." The danger of a Quake monster doesn't come from its abilities, it comes from how those abilities overlap with other monsters, with surrounding architecture, with where the player's attention is focused, and with how his movement is constrained.
Meanwhile, the whole Quoth menagerie has homing shots and perfect leading shots and hitscan attacks with no anticipation frames and every new dude is like his own miniboss.
this is supposed to be the screenshots thread
You're right!
