Rift Herald should reward junglers rather than just top and mid laners
Having the Rift Herald give benefits only to laners is unfair and makes it a worse choice compared to dragon in solo queue
Smiting to kill Rift Herald should extend the duration, or give camp related buffs, so junglers who often enter lane to help push down objectives can still benefit as much as a top or mid laner (assuming they didn't take smite themselves), having extra time for their buff to compensate having to pick it over dragon, along with compensation for running around lanes to help.
