Looking to start Trials of Osiris soon. I'm 306 light (not the best, but I think skill is probably worth more than raw stats). What tips would you give to a ToO beginner hoping to do flawless one day? e.g. What type of weapons tend to be best? What light level is advisable? What are good tactics to use in the games themselves? Should I remain in place and snipe from afar? Should I try to sneak around the map and use the shotgun? What things could happen to screw up my game? What emergency tactics should I use if -blam!- hits the fan?
