This Battlemech indeed doesn't have "strong" instant damage output like the Meta-fied battlemechs that a few players tend to flock to and it has a "downside" a few players would whine about, which is low slung arms, however this Unit has potential because it's size (almost reaches the same size of the current hunchback and it's skinnier), It also has possible quirk buffs and uses as a Sniper/Harasser which will increase their damage by the end of game (maybe 300-600 on average).
Sniping you can add around 2-3 Large Lasers to soften up the target for your team or mount an ER PPC and poptart to soften up your enemies like the shadow-cats do it, as a Harasser you can use small ballistics like the RAC and AC and walk around the map and just annoy the hell out of that LRM Atlas or maybe the Laservomit Cauldron Born.
All in all this mech would be a fun addition to this game would most likely add some nostalgia to the community, people wanted the Urbanmech so badly but people almost never use it so it's safe to add the Clint
TL&DR
The Clint is a fun and nostalgic mech but wont be as "strong" as the SRM assassin or SRM Bushwhacker, but it can be used as a sniper/harrasser to get some damage in.
