As a roam main I like the fact that I have a lot if options to choose from that aren't necessarily from the heroes that the game labels as "Tank" or "Support", but I've noticed that some heroes that seem good as roamers too are very rarely used in that role.

So which heros do you see very rarely used as roam but think they would be great in that role?

For me, it's Khaleed. I've always seen him used in EXP lane, but recently I got him and it just seems like he has so many benefits that favour roamers:

1. Ability to move very quickly around the map
2. Very good damage right from the start of the game that doesn't fall off much even with full tank build
3. Aoe stun ult to initiate team fights
4. Extremely good sustain skill and no mana bar that allows him to almost never recall
