Really the Quickdraw is akin to a shield covered in spikes. Played right this mech is nigh on unbreakable in a straight engagement since its Jump Jets let it constantly rotate in fresh armor against adversaries. For me personally I've killed Illa Chansaws, Laserbacks, and even a Brawler Staker because while they could only afford to lose 30% armor, the Quickdraw could afford to lose 80% and still keep fighting. This mech is a tough little brawler on its own, but when in a team it can use its armor to shield allies and let their heavy damage investment hit the targets they need to. Some people might not consider it enjoyable to play a mech who doesn't get 5 kills every other game, but for those who can pave the way for teammates, the Quickdraw is a fantastic mech to use for that purpose.
The quickdraw is a fast mech that has quite a large torso and when I first bought my 5k most of the times my side torso is destroyed first and then I get cored. The quickdraw 4G seems better though since it has enough hard points for my build that I want which is LRM and SRM and medium lasers. When I play the quick draw I get potshots by using my jump jet's and then shooting medium lasers or firing my LRMS which work and then when the brawl started It get's fun
