I understand where you're coming. Personally, I've looked at all monsters and kind of planned which weapon(s) I won't be using against them because of stupid monster moves or just the size of them lol.ye I know, but you can't get some of the juices from endgame monsters w/o using marking. and marking sucks. I've got 70+ hours with IG now and it still feels too dependent on lucking out.
It's fine in multiplayer, but you can get really screwed with endgame singleplayer quests if you can't manage to get red juice.
