New Rift Herald OP?

Just my thoughts, but after seeing the new rift herald and how much damage it does to turrets (roughly between 1/3-1/2 of a turrets health) I feel like it will only make the game more snowbally.

I get it, Rift Herald is super hard to get and will take a ton of resources, but I feel like once you get it it's gg. The odds of a team that's behind getting it is very slim, so usually the teams that will have it will be the ones that already have an advantage. So now you're down gold, behind in turrets, trying to turtle, and then this huge monster comes out of no where and takes 1/2 of your turrets health....

Also, if it was a one time deal maybe it makes sense, but the rift herald has to be killed!! So now you have to devote more resources into the lane with the herald while the team that's ahead creates even more pressure else where.

I get that even the current Rift Herald is usually for teams that are ahead, helping them close out the game even faster/safer. But the new Rift Herald I feel like is the end for a team that's behind. You put him mid and send the whole team with him, probably gonna take down 2-3 turrets. Put him in a side wave and send one person with him, now you have insane map pressure and can pretty much take whatever you want on the other side of the map.

That being said, I am really looking forward to seeing how it plays out. I don't want to completely trash an idea before it actually goes live, these were just my immediate concerns when I saw the new Rift Herald.

Thoughts? Am I overestimating the new Rift Herald?
