Don't get Mark/Dash on Blitzcrank/Naut/Thresh.
Your whole kit revolves around displacing the Enemy Team (specifically their carries). Putting yourself a mile out of position with Mark/Dash completely defeats the purpose of hooking someone. Great, you hooked someone... at point blank range... several hundred units ahead of any follow-up from your team. Good job.
Literally the only exception to this is using Mark/Dash as Thresh and Lantern-ing in something like a Wukong/Alistar etc who elected not to run Mark/Dash themselves.
