It should ideally be something with jump jets for good mobility, and is some combination of fast enough and powerful enough to run or fight your way out of trouble when bothered by one or two lights.
It requires a lot of experience and awareness and you always need to have a well thought escape route back to your team.
I snipe all the time with my Gauss erppc Timby, usually from 400 to 800m away.
Regarding the issue if high damage no crits or kills, the problem could either be you or your team.
It could be, for example, that you are doing damage at a super slow rate and running your weapons all over enemy mechs. It could also be that your team just suck, has gotten itself into a terrible position, has done no damage and every mech you hit is fresh.
The latter has happened PLENTY of times to me in t1 solo queue.
As a sniper, you are engaging targets of opportunity. That means you can't force the fight to a mech that doesn't want to. You can't advance on a position to get to damaged mechs, you can only see what's on offer and take your shots.
If you take a mech like a timberwolf on a flanking sniping position, you can make certain positions untenable for enemy mechs, and force a retreat or extract very heavy cost PROVIDED YOUR TEAM PUTS ANY PRESSURE ON THE FRONT.
If your team does nothing, you are SOL.
I've had games where I was the only one putting in work on the team, putting in 700 to 1000 damage where, seriously every single person i lock has at minimum yellow armor. I'm shooting as fast as heat allows and team is just disintegrating like wet napkin.
And then at the end one of the 100 dmg potatoes pipe up: NO kills you suck!
Really?!
You expect to hand me steaming horse manure and get out golden victory? What do you think I'm in, a kdk3?
