My thoughts on how to nerf what makes boldur a problem, while giving him a clear line for an alternative play-style via helix options, a fun way to play that might draw more people to playing him.
Boldurs passive speed without his axe is too useful, the axe is tossed primarily just for the speed bonus.
The Axe Ricochet helix conflicts with this passive bonus, and the Axe Toss cooldown reduction bonus conflicts with Axplosion.
Too much skill combo burst. (paired with everything else)
Change Runes of Power to no longer make Axe Toss explode
Instead, it makes your next Axe Toss a free cooldown. Essentially he can throw the axe twice. Given that Axe Toss has a base damage of 200 and Axplosion adds 220 in an AoE, he’d still do less or similar damage by hitting the same target with both axes and not in an AoE (bleed doesnt stack)
Pinballer is godawful. You basically get to knockback/stun your target and LOSE the ability to follow up on it with meaningful damage, he’ll be free to run away before you can get back within range, this is a joke pick, it says "I have stunned you but instead of punching your crit spot for 2 seconds i’ll fly away"
Buff pinballer by making the Dash apply 16% vulnerability for 2 seconds. This would make it more of a “i help you get kills” move, instead of “i kill you myself”, his allies get 2 seconds of 16% bonus to capitalize on it. He could toss his axe at them in the air though, and thats badass. Before anyone calls it op… Long Distance Dash is the usual choice, thats the one that lets Boldur dash super far, making him extremely hard to catch and you hate when he does that. Thats a big trade.
Few people take the left option, most people just quick melee because its HIGHER DPS than the fist, and much easier to land. It seems they tried to make “punching” boldur a thing, but it never really worked out (the mutation is horrible)
The Funfix. Change stunning blow to a helix that lets you axe toss while blocking. Essential to an Axe Toss build? Maybe. You can safetly throw out a few hundred damage now and then but your shield is half strength and you cant run with it.
And thats about it. He loses his AoE burst damage and gets access to a fun/gimmicky axe tossing build, fully fleshed out he could toss his axe every 7-8 seconds + double toss for his ultimate, but he’d lose out on a lot of survivability (Death and Taxes in particular is 740hp alone for a 20% axe toss cooldown reduction) and mobility to become a melee hybrid who can harass from range.
Also -3% quickmelee damage
