Any suggestions?
Any fighter tagged as a Fighter/Assassin is pretty solid at chunking towers
Of note: the damage you deal to towers is actually 100% of your base AD plus the higher of either 100% of your bonus AD or 40% of your total AP.
Towers are completely unaffected by armor penetration and cannot be critically struck (though they do take damage from Sheen/Triforce/LichBane/Iceborne).
AP+AS champions like Kayle can actually be really efficient when taking out towers due to AP actually factoring into tower damage, but for the most part you just want a champion with strong %AS steroids that wants to build a lot of AD.
Jax is probably the best top-lanner specifically for chunking towers at the moment.
