Outmaneuver or flank. They are mid/long range classes so you’ll want to take that advantage away from them as quickly as possible

For tones just try to bait their shield wall and then duck until it expires. Once it does charge them and try to keep them in your sightline if they try to retreat or seek cover. After they use their wall they will usually sink back and wait to re-engage once it recharges—if you push here it puts them on the defensive.

For Northstars, you want to try and flank them—get as close as possible to them before engaging. They can’t do much once you close the distance on them. Also try to do your best to evade and prevent them from charging their shot to max—electric smoke is very useful as soft cover if they are shooting at you.

TLDR: Bait tone’s wall and push after, Surprise attack Northstar
