Hello, I am Sirkiller98 and I still believe that Lucian is viable even in today's meta.
I have not played a ton of ranked games in the past few seasons due to college but I did manage to peak at plat 1 during season 7.

For purposes of this section, I will be talking about Lucian MID. The Main conflict in picking Lucian mid is that you must take into account the damage orientation of your team before you lock this character in, unless you are like me and could care less what 4 inconsiderate idiots think of your choices, not like they are the same rank as you haha. (seriously if you piss off your team, you will probably loose).

If you are playing Lucian mid, your goal is to GET AHEAD IN LANING PHASE. If you cant manage to do this then DONT PLAY THIS CHAMPION MID. If you fall behind vs. most assassins and control mages, they will just murder or one shot you. This champ is amazing at 2v1's once you get a lead. use your life steal to heal up and keep trading with your opponent.
