since rumble is disabled, who should i pick against vlad top lane?

That depends on what you want to do.

Do you want to simply survive Vlad and farm up for later on?

Do you want to push hard and roam instead of facing him?

Do you just want to beat the crap out of him until he's useless?

There's more situational picks that depend more on the enemy jungler and how good you are with the particular champion cough Singed cough but this should help you get started on deciding who to pick up.
