Illaoi's damage

So when i encountered a game on 6/19/18 i fought an illaoi main no problem no issue there not saying you can't main anyone all im saying is that she wasn't even close to being good with her champion, level 6 when i am playing yorick she had no mana but still enough to cast her w and also delete with no damage items at 6, her tentacles doesn't even say what kind of damage it is so there is no counter play or counter building when it comes to that. riot claims that her tentacles do not do true damage or magic or physical, it just does damage. I have been playing this game since it wasn't even popular for 8 years I witnessed this game growing from the ground up and now i see it being destroyed from the the sky down all because riot wants to no nerf champions that first off scale ungodly amounts with no cap and also make champions that can 1 v 5 a team without any healing items or abilities being received and still able to take zero amounts of damage all because her tentacles provide a slow,lifesteal,some sort og untitled damage, and respawn every 8 secs, her ult with amount of enemies around will be tentacles so when she walks into a 1v5 she can pull a soul and it now has 6 tentacles adding the number of tentacles she already had around ehr which equal up to a minimum of 10 tentacles around. which means five people at the same time for the same duration take untitled true damage and life being taken from them and given to illaoi which makes her have sustain right? wrong riot also claims that her tentacles can not be countered by liandry's by ignite by mortal reminder or by dot damage. so im am so concerned for this game because last thing i would want to see is another illaoi. illaoi was a mistake in the game that they should had never made.
