well all i can add is its definitely slower paced AT TIMES than traditional MMOs but when you get in to combat its fast paced.
Investigation missions are fantastic, im sure you saw me post in shoutbox about one in particular that had me referencing dutch painters, bible quotes and translating latin, failure to do so can result in false leads which are a fantastic addition.
Sometimes the missions involve following trails, that you need to take your time to look for carefully, can be annoying but inevitably rewarding.
Also at times it does feel like your banging you rhead against a wall, but all you have to realise is that by going away doing something else and maybe gaining another tier in your chosen weapon or unlocking that new ability to complement your hinder/burst/leech abilities could make ahuge difference.
Juggling skills to suit your build is needed pretty quickly into the game, you get no real tutorials, no hand holding, and do die a lot.
You do get teh modern mission circles on minimaps at time, though not for tracking or investigations usually, even when there are circles youll find yourself having to hunt inside the highlighted area to find whatever you seek, it wont always be in teh centre. mission interactables do glow red but only when you get quite close to them, so not from half the map away like some otehr MMOs.
all in all im finding it fun. It will be a niche title, it will scare away the gief it now crowd, and did i say im enjoying it
