PSA: If you have a Vladimir mid lane, don't expect him to roam
My god, the amount of times I've been pinged and flamed because I don't roam in other lanes when I play Vlad during the early game. Like, what do you expect from a late game hyper carry to do without items? It's like asking Nasus to roam and gank mid during the lane phase. He has no damage, no strong healing, he isn't tanky, he has no (hard) cc, he's slow af. He needs at least 2 items to start doing things. So unless he has dominated his lane and/or he is ahead, just let him be.
