Manaflow band makes it so you don't have to worry about mana at all.
It has gotten to the point where the enemy can spam spells off cooldown and never run out of mana, meaning you don't get a break in having to constantly dodge abilities, or take damage if they are point and click or you didn't dodge. Back in earlier seasons poke champions had to manage their mana, lest they run out and either have to back or become very vulnerable to all ins, meaning you get breathing room to cs and sustain your hp with pots. If they wanted more spell spam, they had to sacrifice combat stats to take mana regen runes, making them vulnerable to all in fights. Not to mention the poke hurts even more than before due to scorch, comet/aery, and the sorcery tree adaptive bonus. This is especially worse in the botlane because most non melee bot lanes don't go into resolve, so they can't mitigate the poke making the lane super snowbally. So if I play botlane I have to keep dodging ezreal/varus/jhin poke as well as the insane damage from brand/zyra/velkoz/xerath. Having to endlessly dodge poke, (sometimes I can't even dodge it as I am going for a cs) is really toxic because there really is a lack of counterplay. The latest champion zoe only exacerbates the problem as her low cooldown, low cost poke is nuclear, and she has cc so you can't all in her effectively.
