Yea that sounds good ae. Anther hero ithink would be cool is one with a move that requires skill and timing lyk potm arrow or pudge hook, mab lyk a snake that fires an poison shot and it acts as lyk a potm arrow but with poison, lyk gale but a stun, or this move if it hits them increases damage taken over a period of time.
The funnest heroes i find are always those types where you skills work well in combo and require a certain degree of skill for example potm pudge invoker so i rekn thats what a new hero should have

Cheers
