I'm going to point out a few particular bits I found important in my quest to learn how to not be a smouldering pile of slag with 90 damage and a sense of shame. While mediums are unquestionably the least forgiving to piloting errors, (at least until knockback is reinstated and Lights become... interesting.) they also have great potential to fill any role necessary in a team and provide ample support.
This build also largely works for the Cicada and Dragon, also mechs I love, though I pilot JJ'd Mechs exclusively thesedays.
1: Speed is not how fast your groundspeed is, speed is how quickly you get from point A to point B. In this regard, JJs are glorious, though you only need 80kmh+. When running, faster targets almost always duck and weave between building or around terrain in an attempt to stay in cover. Circumvent this behavior by running in a straightish line towards where you think they are most likely to go. This is often much quicker to reach than simply chasing their exact path, and can often result in you catching mechs with much higher groundspeeds than your own.
2: Stay with your team. Mediums are not solo chassi. 80kmh is more than enough speed to outrun or stay with your heavy and assault compatriots, and use them for cover. You can also allow enemies to engage these much more threatening targets, and then easily and patiently core them or hit them in the diaper as your friends take all the damage. (They're fat, they can deal with it.)
3: YOU ARE NOT A FATTY. So stop trying to boat. Using light-weight weaponry effectively is far more empowering than simply having a lot of long-range weaponry or weapons perceived to be "larger". Having 30FP and being heat stable and fast is far more important than any perceived FP number. That weight is needed for backup equipment, ammo and Engine Size. While some might argue that this is a matter of personal preference, I feel that all mediums should take max size engines, STD or XL depending on shoulder vulnerability, and whether the mech has JJs. I know medium players like to brawl sometimes, but the chassis is simply far more effective in the role of a support mech or indirect brawl assistant than a brawler. Come on, guys, the things only weigh 50 tons.
Play cautiously, learn from your mistakes, and enjoy!
