Hero executions (behind a very small pay wall if that is what it takes to bring them back)
More frequent armor sets
New Heros
New feats and perks that heros can use or gain in their arsenals.
I generally agree with everyone else when it comes to the wonky dodge recoveries that do not at all feel like dodge recoveries. Once the animations are fixed and shinobi has the bash wall bash removed these hero's will be viable at all levels of play again. Raiders faster stampede charge alone makes him more viable in 4's again, even duels. One thing I have really wanted from this game is infinite reputations for any hero played. Rewards aren't really needed. Just let people show how much time they dedicate to a hero why not. Reputation is one of the reasons people play this game anyway. A really amazing thing in regards to reputation would be to show what every hero would be if there were not cap on the reputation. That way people get a true perspective on the time put into the hero, and there would be no immense grinding involved.
so honestly i dont respect someones rep as most players who complain about rep have 0 honor and also are the same people who I know gank but also play pve and say chill its just bots and no some heroes do need buffs shino is one of them as he is really not friendly for new players let alone vet players
