Zz'rot portal needs to be removed or fixed

I'm sure everyone has already heard enough of complaints about this item but seriously it feels so cancerous playing against it and so boring. For disclosure, I'm not that highly skilled at the game as I don't play ranked. A lot of my games are normals in summoner's rift with a bunch of low elo players so teamwork in most of my solo queue games is not that strong among everyone.

So the story goes, I had a game where I played teemo top lane, yes I know it's cancer as well but I was facing a lee sin top. I completely crushed him killing him 3 times before I hit level 6. All was well until he bought zz'rot portal as his first item. Not only was he tanky so it was hard to kill him even though I was stronger as he could just run away with ward hops and was tanky, but the guy would literally just hide behind his tower and place a rot portal at his first tower. I built normal teemo items such as liandries and nashors first but then you can't even push hard enough against rot portal. To push you would have to constantly auto and out push the rot portal while over extending, then under their tower you can't really fight them as they are tanky and you are squishy. Of course you could go tanky but then as a teemo I find I couldn't out push a zz'rot portal going tanky. I knew an option was to buy my own rot portal from the start but I find that would make the game so boring because me and lee sin would just sit around as the zz'rot portals negated each other and no towers would get taken and no skirmishes would happen between us. I probably don't know what other things I could have done to counter zz'rot portal but I do think it needs to be heavily nerfed or removed.

The lee sin player literally just sat behind his tower and spammed taunts, dances, laughs ran around aimlessly and would get farm from pressing q on minions as well as rot portal. I think it's ridiculous how rot portal's voidlings can kill your minions and give gold to the person who placed the rot portal, but then you get zero gold from killing the voidlings. The lee sin literally got farm from a safe distance literally doing nothing at all, he just sat under tower occasionally walking up to q minions and if he felt in dangered he can ward hop away and would get free farm from zzrot portal and then farm safely under tower so I couldn't attack the tower because if I tried to attack his tower he could easily jump on me and do massive damage because base damage is still relevant to squishy teemo me while if i try to attack him under tower the tower and him could out damage me along with a jungler possible of ganking me for over extending. Another problem was that my minions never could really even attack the tower because their attention was constantly focused on the rot portal voidlings so the tower and lee sin would kill all my minions before they could even take a crack at the tower since voidlings would spawn constantly and take the minions attention away from the tower.

I find it dumb that the voidlings just run straight to towers and dont care about the enemy minions, but then enemy minions dont just ignore the voidlings either. If the minions just ignored the voidlings, then the minions wouldn't be halted by them. I don't know what a good way of fixing rot portal is as I find that if you changed it so rot portal didnt give you the cs when your voidlings killed a minion, I find that would be sort of bad as well since buying a rot portal would be bad because you could lose out on farm with voidlings ksing your minions. Also I think making minions ignore voidlings as voidlings ignore minions would just make more problems as voidlings could ping towers for free without being halted by enemy minions. I think the whole idea of having an extra split pusher from an item a bad idea for league because the only way to really counter it is to buy another one to negate it's pushing power or send 1 of your teammates to take care of it is a bad idea. Just reminds me of thragtusk in magic the gathering, basically one of the most versitile creature that could be played in any deck who's only best way to counter the guy, is the have one of your own as he was so strong. He made many decks just completely useless similar to how rot portal makes certain strategies useless.

I know a lot of people say reisistances without health isn't so powerful or that everyone only buys zzrot portal as a third or fourth item but that's just not true. Thornmail was pretty strong at one point even though a lot of people say it's a noob trap because it only gives armor and no health or magic resist. Another thing is in my game that lee sin's first item was rot portal and I had no idea how to counter it other than buying my own rot portal but then he still wins because without rot portal I completely dominated the lane. With both of us buying rot portal, It's no longer me dominating, its just me and him both neutral as I have no way of killing him and he gets farm for doing absolutely nothing but placing a rot portal.

Some suggestions I think would be to make the cooldown of zzrot portal's active extremely long that you cannot place another one shortly after the last one dissappeared would help in the case of lee sin literally sitting back behind tower chilling drinking coconut milk while his zzrot portal would farm for him. At least make it like double the time a zzrot portal lasts until it dissappears like say if a rot portal lasts 40 seconds then the cooldown is 80 seconds as an example. But personally I think the item should just be removed because having something pushing other lanes while champions arent there is unfair. I guess I should just start buying zzrot portals no matter the role whether I am adc, or whether it doesnt go with my champions build path such as teemo, zed, ahri, or lucian. Thanks riot let me know what you think. Please don't come on here telling me I am a noob or scrub etc I am only giving my personal opinion. The only closest thing that made the game hard to play against besides rot portal was just how tank items outscaled damage items and I would get destroyed by an 0/3 enemy laner once he had tank items and I was squishy as my damage became useless while his damage was not because his base damage was stronger and I had zero defensive items. YES I PROBABLY SHOULDVE BOUGHT AT LEAST 1 DEFENSIVE ITEM I KNOW I KNOW but I am lucian or zed and I did good in lane probably like 2/0 with more cs than enemy laner but a random 0/3 irelia can still 1v1 me fair right? I'm not trying to be toxic if I come off like it, I just am frustrated at some things that happen in my games that shouldnt happen.
