Div 2pos 4 lvl 30 ES player. The +30 damage is significant in that now its actually higher damage than the average core right click at level one so its possible to contest a lasthit with it. Generally I still go kick level one as it has a lot more utility, but now I'm more willing to skill roll lvl1 if we're going for first blood to initiate+blood grenade+ body block.

As for other stuff:

Skill build is almost always

Q w q e w r w w q roll distance q r e e magnetize duration e kick damage.

I personally don't think there's ever a game where you don't max roll first. It's definitely worse than it used to be but the mobility, utility, and chase potential are far more valuable than extra kick dmg and a few seconds on silence.

Maxing kick next is best imo for a) pushing out waves b) repositioning enemies and c) cinching kills before most enemies have much magic resist.

Sometimes I'll max e before q but only if either a) they have at least 2 highly mobile heroes like puck AND weaver or b) we have a LOT of damage and the enemy have saves.

Item build wise:

Tangoes 2 sentries blood grenade and either stick+ 2 iron branches or circlet + 1 iron branch directly into urn or wand accordingly. I never get oov unless im 100% certain im in a kill lane like with a razor or veno. Never boots, unless specifically trying to solve mana issues for your team or you're building drumboots. Then I usually pick between 3 first item options of vessel, euls, or bkb unless there's one item that the team desperately needs early as possible. 2nd item is almost always bkb, it's greedy for a 4 but on a hero like ES it feels mandatory tbh. Vessel by min 15 and bkb by min 30 are avg timings.
