Funny enough,
JESTER Chuckles is my go-to for challenges. I tend to think of it as a 'fat Jenner'- it's a fast 'mech for its weight that keeps up with slower lights and fast mediums fairly well, and performs as an excellent harasser. Depending on how I'm feeling that day, I may or may not use the remaining 1.3 tons to throw an additional ton of AMS ammo in the arm and a little bit of armor- usually not, because people love to take the arms off Jesters (and energy-hauling K2's) under the assumption that the weapons are kept there for the sake of weapon angling.
There are two tricks to the way I use Chuckles-
1) The medium lasers in the CT are one to either side, so I have two firing groups- one for the left side of the 'mech and one for the right. If I feel like peeking around a corner, I can use one group, or if I want to run cooler, I alternate groups. This lets me control my heat generation well enough that I can always alpha strike if/when I feel like I need to.
2) Whenever fighting more than one 'mech or anything fast enough to outmaneuver Chuckles, I perform dart-and-peck maneuvers- I get in, I zarch one location with 30+ damage, and then I vamoose. The damage is enough and comes out fast enough to take out a location on lights and cripple one on most Mediums, and if I feel like I can get in two alpha strikes on something heavier I will- but I'm always moving around, and I'm always ready to haul creepy neon grin rump out of wherever I am.
Weakened locations are easy to take out in this fashion, the dual AMSes let me provide added umbrella or some degree of protection when TAG and NARC are flying around, and I leverage the speed of the thing
constantly. The Jester does precisely two things of note- go real fast, and haul dual AMSes- and the way I operate it and the way this build is put together uses both.
It's my only Hero 'mech, and I'm fine with that. It does the job -very- nicely.
