I haven ' t seen such ball control from Mkhi since Berbatov <| sep |> While it is important to poke when possible on Janna , that ' s not her primary job . In lane her goal is really just to keep her ADC even with the enemy ADC . You usually can only get kills in a Janna lane if your jungler ganks with hard CC or if they allin first , but Janna is exceptional at baiting and keeping her ADC alive . You can actually pick up kills more often than you think . Janna is one of the best late game supports due to how phenomenal she is at peeling in teamfights . So to answer your question more directly Yes , you should only auto harass and shield your ADC in lane . W and especially Q are not worth the mana cost in lane . DO NOT use Q to harass in lane , it ' s relatively hard to land when they ' re not chasing you and it costs a lot of mana for little more than an autoattack ' s worth of damage . W also should rarely be used in lane because of the mana cost and due to the fact that the passive movespeed bonus is lost while the ablity is on cooldown . Q and W should be saved for allins or if one of the junglers ganks . Due to the charge time of Q , it ' s nearly impossible to land if they ' re running away , so if you know their flash is down and you just need a bit of extra CC you can flashQ . If you ' re level 6 and feeling feisty , you can also try to flash behind them to ult them into your team , but this is very risky and I only recommend you do so if you are very experienced with Janna . This is a very high risk play that more often than not just wastes your ult and your flash .
