The law was expected to reduce kicking. It has mainly relocated it.
When the 50:22 was introduced, the concern from supporters was that it would reward a conservative game built on territory rather than possession. That has not happened in the way anyone predicted. Kick counts per match in the major leagues have stayed broadly flat, and in some competitions have fallen slightly. What has changed is the kicking map, and quite dramatically.
Kicking earlier, not more
Teams now kick from further out. A side in its own half with a plausible touchline has a genuine incentive to go for the corner, because the reward is an attacking lineout five metres out rather than a contested contest forty metres upfield. Kicks that used to be played inside the opposition half are now played earlier, from positions where a mistake is cheaper because the resulting field position was never good.
The space that opened
The defensive response has been to drop a winger deeper than was previously normal, which in turn opens space in the fifteen-metre channels. Several sides have built their entire attacking shape around that consequence, selling one space to buy another. The law has not made the game more conservative; it has changed what a good position looks like.
