That's not how tradeoffs work. When perching, Cait would be a making a deliberate choice to no longer waveclear. This would be a major decision point in lane, where her poke range wouldn't be that long overall anyway (she'd need to reach level 9 for maximum poking power, by which point the laning phase would be over). She'd never be that safe, and enemies could easily take advantage of her positioning for offensive or defensive purposes. Currently, by contrast, she gets to land a ton of guaranteed poke simply by hanging around in lane, to no cost in waveclearing power.
