I wish support can get a mana item without cdr

Most of support items offer CDR and mana regeneration. But I feel like enchanters are the ones who always run out of mana first. They got their own line of items which are ''mana regeneration'' items but what they really need is mana items without cooldown reduction because now every support items gives CDR. You're going way up above 40% cdr which is a waste (well, unless if you go transcendance, but you're getting a free 10%cdr yet AGAIN)

Lich Bane Lost Chapter Luden's Echo Manamune Mejai's Soulstealer Muramana Righteous Glory Rod of Ages Sapphire Crystal Seraph's Embrace Sheen Tear of the Goddess The Dark Seal Trinity Force Trinity Fusion Zeke's Convergence

The only okay mana item I see that gives no CDR and is for enchanters is Rod of age, which basically no support champions get.

I love to play Karma, Nami, Sona, Morgana and Janna... I feel like manaflow band is a must on them or they'll run out of mana too easily.

And guess what, Shurelia is comming back (which is an item I can see enchanters rush) with CDR again and no mana regeneration OR mana.

I mean, how are enchanters supposed to manage their mana when all they can get is mediocre mana regeneration items and manaflow band (and maybe biscuits) ?
