Noob question to get on topic a bit: how hard is it to actually get to Mercury? I haven't even touched Trials, didn't have anyone to play with before and I only loosely know how it works.:
The answer here depends on a lot of factors. Most importantly:
-Team skill, experience, communication: For a team with 3 Trials virgins like you, Mercury would be basically impossible unless you're extremely skilled. For a team of 2 very experienced players and yourself, Mercury is very reasonable. These "carry trains" depart the station frequently and generally prioritize Mercury first timers.
-Lucky match making: Most Trials teams average ~50% win rate and ~1.0+ K/D. Some a little better, some a little worse. If you match against scrubs 7 times in a row, Mercury can be a breeze. If you match against Triple Wreck 7x it ain't gonna happen.
How many people have every exotic weapon leveled up already?
Currently doing Hard Light. Next weapon will probably be Monte Carlo.
Yeah every exotic weapon and armor (excluding Bones) has been maxed for a while now. On one hand it's a "waste" of resources for a huge amount of gear I never use. On the other hand it's a video game and I enjoy having the collection, haha.
