you could say they have similar trajectories with starting off hot early on in their val careers , a middling period where they were shooting but not getting results and a recent resurgence only tenz had higher highs and lower lows.
but to your point about keeping the position with zekken on team, let's be real here zekken did not take the op role from tenz bc he's a better oper but bc tenz is playing agents that shouldnt op often to begin with but he still does occasionally to keep opponents on their feet.
