I just want to highlight a couple of my Hero mechs that have questionable quirks.
 
Dragon-Flame: Laser Duration +10%
 
HUH? Why? The 4 low-slung arm mounts are just so OP they needed to be nerfed?  I don't get this at all.  Grrrr.  If anything they should have added energy quirks, not nerfed them.  Now my 4 ML are even more crappy, especially when they only hit rocks most of the time.
 
The AC20 quirks are ok, but I much prefer a Gauss in that location and the perks aren't enough to make me change my config.  I'll take the increased range and velocity, though doubt I'll notice a 7.5% increase (2150 vs 2000).  
 
So overall, my play in this mech has been nerfed.  It's a DRAGON. 
 Jagermech Firebrand: Tier 2 vs. Tier 3
 
Jagermech Firebrand: Tier 2 vs. Tier 3
 
All other Jagers are Tier 3.  I don't get this one either. There's nothing really special about the Firebrand to make it a higher Tier over the other Jagers.  Sure it can take a bigger engine, but who does that?  In fact, it's got reduced torso twist which makes it less desirable than a -DD or -S.  I'm confounded.
