Why
Caitlyn instantly forces a range match-up where you have to ‘pay’ to enter. Lucian loves setting tempo with dash + sharp trades; versus Caitlyn, dash often just crosses a safety zone, leaving you inside with no clean exit if the trade goes bad. The more you feel forced to push, the more she calmly waits with range, traps, and zoning.
Lane impact
You can lose lane without inting because you get chipped down: an auto here, a headshot there, until you’re too low to threaten. The worst case is when she controls wave and turns every trade attempt into priority loss, delaying resets and preventing you from using your early identity.
How to play
Look for real windows, not imaginary ones. If Caitlyn still has net and trap control, you don’t want a long trade—you want her to misstep first. Manage wave to force stressful last-hits, then sync your entry with support CC, because alone you’ll often just dash into her comfort.
