has flat out damage and does barely any damage to tanks. She excells at catching a squishy target off guard with her bind and CC him/her to death. You want to kill the adc for example if it's snared for some time. A tank doesnt give a crap.
Not good, but not bad either against tanks. She excells at bursting someone down with spells and get away with it, hence her high mobility. She has some true damage, but not enough to be really effective against tanks.
Alright, this guy can actually do damage to tank, but he is so easy to get close to since he is only able to cc 1 target. He is decent against tanks, but the lack of mobility will get him killed quite easily since he needs to get close. However, I do say, that he is a decent pick.
How is this guy supposed to be good against tanks? He has firstly, one of the lowest winrates, and secondly, he does not do enough damage to bring tanks down. Just no. There are far better champions that are able to destroy tanks.
Now on to
. Build rylais and liandries on this guy, and combine that with his passive and he is a tank shredding machine. He has a good amount of poke in the laning phase and also out laning phase with his W and can stay fairly safe with his slows on the rylais and stun on his Q (when target is ablazed) He can kite so well with these items and does so much damage on %health.
