Advice for Tempest Aquilons vs Stealth suits

I really struggle vs my brothers new stealth suits. We’ve been playing on volkus (we randomized the mode so last time we played Energy Cells)

The stealth’s can ram up vantage and they can swap right back to conceal making it very hard to touch or do anything to them. I feel like they negate the sentry, plasma, sniper by design. (Tbf I hate the sentry and wish I could play an extra trooper but that’s just a tangent.)

I’d appreciate any insight into that matchup
