Give Blink a huge, dirty nerf. Said it patches ago and I'm saying it now. Half the heroes need a blink to do their job and the other half will still get one because it's just too good to really ignore. Same goes for euls really, though then again with Blink being less of an omnipotent positioning tool countered by Euls, Euls might get weaker as well.

Tusk's Walrus Punch needs something. It's like a shitty Jinada you can only get at level 6, and his other skills don't synergize well enough with it to really justify it being so bad. It doesn't even scale well with levels. Perhaps a longer air time, or maybe some better crit-values every ult level? Perhaps add base damage to it so it has better burst early? Hell, he's the most anime bullcrap hero running around already, make him use the power of friendship to borrow 10% of every allied hero's attack damage close to him to crit with the force of your whole team. I don't know.

Pugna and Leshrac are both kinda gimped by the punishments for early pushing, and are both lacking for all sorts of reasons because of that. Seeing that Leshrac already is more or less a walking nuke and they already tried pretty hard to give Pugna some supportive capabilities in the last few patches, they should further work on making Pugna a viable medic with an agenda of smashing towers and give Leshrac a way to better sustain himself in the middle of the fight. Perhaps Pugna could get better range on Decrep and Life Drain to better position himself in a fight, or some better disable/control to his Decrep(maybe click it another time to end Decrep prematurely, like Nightmare but on remote control?). Leshrac could probably deal if he could get some better strength game, or if one of his skills would get him sustain based on how many units he hits or something.

Ench pretty much only needs better Enchant dureation that scales with levels, as well as maybe faster healing attendants or something similar giving her more durability.
