I think Darius needs some minor buffs to his base stats, it could go a long ways
The buffs I was thinking weren't very big, they would just help solve some of his issues slightly.
For starters, he has one of the lower base health for melee Bruisers, increasing it by 20-30 at level 1 would go a long ways and wouldn't make him overpowered or anything, just bring him a little more in line for having no tank or sustain in his kit.
His mana per level could be increased, by around 10 to give him some more mana late game, and possibly increase his base mana by 20-30, this buff isn't 100% needed and should be the last one considered among all of these.
Darius's movespeed should honestly be 345, and not 340. He's incredibly slow for a melee and ONLY gains a speed boost IF his enemy is bleeding.
His problem is getting to his enemy, he can stick to them fine. Bringing the base movespeed to 345 would be huge for Darius chasing people down without his bleed stacks and getting to lane a lot faster.
Those are honestly the only buffs he could use to his base stats, his base AD and Armor is fine, along with his health regen, his mana and mana per level are a bit low and his level 1 base health could use a slight increase.
I don't believe these buffs will make him op, but if you disagree don't be afraid to discuss in the comments section.
Downvoting without giving an explanation for why you feel this idea is bad adds NOTHING to the discussion.
to help out? I hope you aren't building full damage on Darius.
