Easy heroes for new players

By far, the best starter tank is Dragon Knight= his E gives good health regen, meaning you are given a good sustainability, he has a decent stun which increases in range after he uses his ult, and his Q is a good medium range nuke, capable of taking down squishies. His ult is straightforward=change into a ****ing dragon and get increase damage and movement speed. Don't try hook till you are good with dk. once your good, try out AXE, or if you find yourself adventurous, practise pudge with bots. His hook is devastating, but missing it can cost you a **** load. That being said, Dk= is decently easy to play. pudge= insanely powerfull once mastered, but a **** and a half to learn how to play.

I think Sven and Treant Protector are also beginner-friendly heroes since both of them are easy-to-use supports, although Treant Protector's Living Armor requires a little bit of map awareness.

I'd say Spirit Breaker, he's really easy to use.
