Veigar and Nasus- Balanced Or Unbalanced?

As many people knew, there are a couple champions in game that can infinitely collect status. , , , . Are they broken? As many of you know, the longer the game, the strong they will become compared to other champions at the same stage. Two of the most complained champions - and . Well here's why - can infinitely collect stacks by hitting his Q, W, E, on champions, get kills, or last hit minions with his Q. The longer the match, the strong he'll become. So late game he will dominate if you don't have enough MR, because of his easy to land "zoning" E, and his executing ultimate. Thereforth in elo such as Bronze, Silver, where people have no idea how to split push, take objectives etc.. Veigar will have huge advantage once he passes the "OOM" stage.(Out of Mana) His stun is almost always up(About 4 second CD or less if you have lots of CDR). If his stun lands, his other spells will also land and that gives him a quiet decent of stacks. ADC classes do not build much Magic Resist thereforth they could get easily stunned, then deleted by . That is also the reason why people hate so much. Basically all you have to do is to build mana, tank, and damage. pretty much sums up the 3 above, maybe sometimes add in a earlier in the game so get tanky and more mana. Now, talking about . What's different about is that he's tanky, unlike Also instead of stun, he has been granted the ability to give extreme slow on his enemy that increases over time. Normally you would see him on top lane because he is, a very, very strong lane pusher. All you have to do is to wait it out, get stacks under your own turret(In low Elo, I do understand that in higher elos people know how to use strats to freeze, push, shove etc ) Basically playing is just a waiting game. The more you play him, the better you know him and the better you'll get at him. His damage is hybrid, that's fine because normally you would go full tank incase you get kited or deleted before you can do anything. Because you have no hard CC. But what's really cancerous about is his Q, a short CD spell that empowers your next AA, and if the unit dies due to your AA, you gain permanent damage on your Q. Well you see, farming as isn't a hard thing. Right now theres alot of items that give heavy tank and plently of mana at the same time. etc. When you go in, your ulti's bonus health, armor, and MR can tank for all the damage the enemy laner do to you, and normally you can out trade them. Especially under ganks, you can just go in and get double kills because of - Passive. Where you get increased lifesteal that's like a maxed out warlords. Which is pretty bull when it comes to your Q, since it's an onhit ability, you gain health and also it could crit(Get that 1% crit runes just because :^)) Thresh and Sion are champions that the stacking isn't as power as the other two. Even in 1 hour games, you could be pretty tanky and do some damage over time but it's still useless because the both of them can't help much infront of lethality and armor ignore. - Well, in lower elo, they can't really be recognized as "Broken"(Completely my personal idea, so don't get pissed off <3) Because it is possible for them to get kited or outplayed late game. The 60+ second respawn timer is enough for your team to finish off the other team and get some objectives down/Take baron or elder drake. Summing up, they can't really be counted as "Broken" just because if they snowball late game, they do burst damage. There are plently of video clips that can prove that even fed and don't do damage because of the tank buffs recently (Items) Thank you :3
