D&D 5E - Lance is not a heavy weapon - Ergo halflings with lances. :D

So, I think the title says it all, the Lance is not noted as a heavy weapon.
Meaning, halflings, gnomes and all small races can use the lance without disadvantage.

I see a Stout Halfling Barbarian running around with a Lance dealing d12 (with reach, I know) dmg to all who oppose him/her.

Keep an eye out for this potential abuse.
