I've been early teching ravager vs heavy tank in my 1v1s lately. I 'member back in the days where the idealized redcomet 1v1 was energycell com morphing and expanding forward while the factory mass produced scorchers, into mass producing ravager. Ravager was nerfed back then, a hit to speed and projectile velocity, which increased leading and time to hit on moving targets, giving players more leeway to dodge with scorchers.
Since then, we've also had superfluid and ravager HP buffs. Due to superfluid, ravager needs an additional shot to kill glaives and scorchers, and raiders deal less dps. A couple assaults have been slowly gaining HP/cost over time (cough hermit cough) leaning more heavily into the tanky but a little generalist, suited for retreat and repair (cough). Ravager has increased hp a little bit, and runs as the little car in the 'tank' line, ravager > minataur > cyclopse. Also, that projectile velocity nerf? it's swung in the other direction now, ravager can hit moving targets OK.
I like the changes to ravager. It's awful annoying to use a unit that literally can't hit it's mark so I don't like slow cannon weapons. Ravager is (almost) unique with it's speed as an assault, shining in flat open ground. Have you tried to use ravager on Ditched? it kinda sucks a whole lot. Also, ravager has trouble maneuvering around fields with metal wrecks. Ravager also still suffers from commitment problems, due to poor turret turnrate, you need to be careful when making 180 degree turns or you will lose an entire fire cycle attempting to point it's barrel at it's target.
I think people should know Ravager is strong and keep using it in 1v1, see if rover truly just beats heavy tank, or if casual veh switch into Ravager is a winning meta. My intuition says that Ravager isn't that dominant, even though I've seen both examples. Let it marinate more.
