My way to balance some champs and classes on TFT

My way to balance champions:

• Evelynn should be 2 tier. Pyke should be 3 tier. Gangplank should be 2 tier.
• Rek'Sai should be 1 tier. Rengar should be 2 tier.
• Maybe Morgana should be 2 tier.
• Yasuo should be 4 tier (and his HP/shield balanced, to be a good all-rounder unit).
• Akali should be 3 tier and her dmg nerfed. Katarina should be 4 tier and her mana cost decreased.

**Ideas: **

• Maybe Kassadin should be 2 tier and he could have additional spell damage (his Q).
• Mordekaiser should be reworked and have his E ability as his ult throwing out enemies a little further or into him (cost 2 or 3 maybe). He also can have his LoL passive or is W as ultimates. I really dislike his Q on this gamemode.
• For Poppy, her ult gains AoE.
• Fiora could be reworked into an anti-CC unit, where passively she can use her W everytime someone CC her to parry it and gaining attack speed when she parrys. So there is no mana needed, his HP may be buffed too.
• This is a secondary one, but maybe make a basic lifesteal item, so more items can be build from it.
• Glaciar should be nerfed. Not just % passive on-hit. I think 2 seconds of CC for EVERY ATTACK it's too much and it cause units to perma-cc a lot of the time. It would be fine but still OP 1 second but can be changed to a 3 / 6 buff. Additionaly, make QSS an item.
• Assassin damage crits to 125% / 325% and they get a little % of change of criting (10/30 for example).
• Mana burn on spells for demons synergy instead on autoattacks, or reworking the passive into burning % mana but burning the same % instead of total.

I can put even more. Tell me what do you think and what would be your own balance changes.
