Illaoi Bugs/Intentional? Five Annoying Things!

So I play a lot of Illaoi (200+ games on ranked, Diamond Elo and #11 Illaoi on NA server). I'm going to put aside the obvious issues with her kit and focus on things that are extremely messed up in my opinion. Please Learn about them and hopefully Riot can help out.

1. Landing an E on a cursed Champion and that champion running out of bounds -OR- destroying the soul does not re apply curse. This does not reset tentacle counter to 3 or the timer.
2. Landing an E on a cursed Champion does not make tentacles attack the newly pulled soul. I do not believe this resets tentacle aggro on the cursed champion either.
3. Tentacles are -clearly- visible to the enemy team through fog of war and can be attacked. They can see inactive and active status as well. This defeats a lot of gameplay choices. Invading? They see it. Defending from an invasion? They see it. Pushed top in and you invade the jungle 9 minutes in? They see it.
4. Your ultimate does not apply to spell shielded units. This is fine. However, it at times absorbs your -entire- ultimate and negates the spawning of all tentacles via R. Old tentacles have the buff and your W is also buffed still.
5. Piggybacking off of (4), your R -will- apply R summoning tentacles through spellshield if you landed an 'E' on the target. For an example, if you pull morg with E then she spellshield, then you ultimate, you will proc R off of her as well as the E. I am sure there are more bugs, but I can't think of more offhand at this time.
