Battering Ram. Engage with shoulderbash or wait until her Q is down to slap her with it. Poor mobility means you can knock her into corners to finish her off. *Do not ult before her or in her presence.*
Battering Ram. Engage with a kinetic burst loaded up so he won't be able to use his F immediately. Keep an eye when he teleports away, if its close enough re-engage with Shoulderbash and finish him off.
Never be the first one to press F in this matchup and keep your distance until he utilizes his. Shoulderbash damages him through his shield. Try not to ult before him and if you do put your shield up immediately in his direction. Godspeed.
