I have been thinking recently about some of the talent reworks and how blizzard is trying to come up with some unique ideas. I have a few concepts that might work well and I want your opinion.

      1. non-scaleable early game talents.

With all these talents that gimp your early game for a strong late game, I want to see the oposite. Give some heroes abilities at level 1 or 4 that super strong for those levels but don't let them scale.

EX) talent one give a 10% bonus at level 1 that scales to change a 100 attack skill to 110dmg,
where as my new skill would give say a new skill that does 150-160dmg at level one but it never scales. So for 1-4 your a powerhouse but at later levels its a dead talent. It would open up new comps to try and dominate early game.

       2. Charges per match abilities. 

Give some heroes abilties that have a finite amount of uses per game. So a melee assassin can get a long range teleport but it can only be used 6 times a match. It makes you choose carefully when you want to blow a charge. Also you could possible give up a talent tier to gain some charges back. This concept can be tied to powerful abilities since it can only swing the game a few times and if you can bait the enemies charges out you win. It also gives heroes a high skill ceiling.
