I love me some
support. He can be a bit toxic tho as is has a really bad habit of taking most the kills, not that thats an issue to winning as a fed brand can really be a boon in teamfights, but that dont be surprised when you adc flames you 4/0/0 score in lane.
My advice is that UNLESS YOU GET AHEAD by a decent margin, i mean a really good early game, not just a kill or two, dont try to build into AP to much and focus more on CDR, MS, mana and basic support utility stuff. The exception is that L's Torment is suuuuper good on him when combined with his passive as that item alone with it means you will always do solid damage.
Oh and always get
. The tick damage of your passive will give you all 3 triggers of it whenever you land anything, hell he may actually be a champ that can get decent results with full
even.
