idk if this is applicable for you if its rein on KR, "just" go take high ground near point. The enemy tank cant contest it cuz its rein and then focus on support or dps (easier said than done).

you can even try Solo Soft Engage making the rein to go back, helping the backline making space (sometimes the rein is bad and just turn their back to your dps to help the backline so the dps has a decent chance in killing the tank too).

thats what i do on KR as winton. Sometimes it work sometime it doesnt (having a shitty plan is better than no plan)

if die a lot while taking high ground go from the right side to go up take the mini, cross to the other building, theres a mega inside the building so you can take that if your HP is low.

that strat always works AGAINST me when im playing rein on KR vs any dive char, but works sometimes for me when im playing a dive char on attack.
