Has Yugioh become TOO broken?

Now, this game has always been about getting to your best monsters before the other guy.
That's pretty basic strategy, get out your main monster with the good effect, and crush the opponent.
First one to the finish line wins the duel.
And as this game progressed, this started being done faster and faster.
Soon, if you didn't swarm first or second turn, you lost.
But that's not good enough anymore.
Now you not only have to swarm, but swarm with boss monsters.

I sat on DN before in a duel, and yes they have cards on there not yet released and won't be for a while,
but it was preposterous.
Summon.
Special Summon.
Xyz Summon.
Special Summon.
Special Summon.
Another Xyz.
Special Summon.
etc.
...

I sat there bewildered at what I can only assume was about 15 straight summons before they crushed my single card field.
Massive crazy effects going on back and forth, playing at a speed at which I gave up trying to read the effects and just assumed they weren't cheating.
Now I know my Deck wasn't even close to competition level, but this was insane.
Every monster can swarm the field by itself, then destroy something, then have a decent attack.

Makes me think that perhaps this game has hit a point of no return with the speed and power of these cards far exceeding anything previously.

The other day, as I was in control of the field ATK wise, they played 1 monster and knocked me down.
A simple Level 5 monster, the only monster they controlled, had 4000 ATK.
Why?
Because it's effect allowed it to have ATK equal to half my LP at the time of it's Summon, which was the full 8000.
Why is a Level 5 monster powerful enough to run over my Level 8 Ancient Gear Gadjiltron Dragon with plenty of ATK to spare?
When did this game get so crazy unbalanced that a Level 5 monster can be that strong?

I think the problem lies with Konami.
In order to force us to buy new cards, they keep releasing cards that are more powerful than their predecessors in effect to the point where older cards are obsolete.
They did that in GX, then did it again in 5Ds, and now are doing it again in this ZeXal era.
The problem with this is, every time they feel compelled to one-up themselves, the card effects become exponentially more powerful than ever before.

Look at your oldest effect monsters.
Usually they have 1 simple effect, that does 1 or 2 simple things, and they tend to pay for it by having a lower ATK/DEF.
Now compare that to a monster of the same level that's coming out in the next couple sets.
There is a drastic difference.

Then there's the Extra Deck.
It used to be home to your biggest, baddest boss monsters.
The ones your whole Deck was geared to getting out that could win the game for you.
Now look at it.
It's a cheap toolbox of overpowered monsters.
You played a single Tour Guide and bust out a beatstick with an awesome effect that you got to SS without even drawing it.

I'm starting to feel like Yu-Gi-Oh has gotten to a point where it's so self broken, it's hit the point where it needs to implode like a sun.
Effects are too strong, individual monsters have too many of them, and being an effect monster has no downside like a low ATK.
Every single card is a brutal play, then your opponent's turn comes, they wipe out your whole field, and it's their turn to SS 40,000 times.

This game perhaps needs a Yu-Gi-Oh TCG 2, start fresh, start balanced, and stop releasing cards that are infitely one-upmanship of last season's.

See also: power creep. As a Penny Arcade video mentioned, M:tG attempts to alleviate this with such ideas as only allowing cards released within a certain time frame to be played in sanctioned events. Possibly the best way to alleviate this is to introduce "incomparables," which means you can't compare the benefits of two items because they function on different scales. What matters at that point is the balance between those scales. This means you don't have to keep making more linearly powerful releases as time goes on because you can make each one impossible to compare to another on an objective, numbers-based scale. The introduction of completely new types of monsters and novel types of effects, such as Xyz and "tagging out," are examples of incomparables in Yugioh, I'd say. Penny Arcade mentioned League of Legends as one of those games that manages to release new champions yet still have incredibly playable old champions because each champion does something unique that cannot be compared to other champions. Same with Yugioh. Maybe Xyz, which many people lamented, is a good thing because it is another incomparable. I think Konami's implementation of Xyz was bad because they were given cards that are so obviously synchro-destructive that it meant they could directly counter synchros, which is not the same idea as what I was advancing earlier.

You got a good point, but this article isn't just for xyz monsters. It's for all nearly broken card such as TGU, Decayed mummy or any other. Really appreciate to able hear your thoughts.

this is why effect veiler, fiendish chain, maxx C, and dd crow exist :/ usually those kind of mass summon decks are 1-shot and then its over. so if you stop it theyre done for the duel. 1 veiler cuts any chain if you veiler the right guy. maxx C means you will draw veiler in the chain. dd crow cuts chains that use grave. bye inzetkor. bye windup. bye dragunity, bye chaos, etc. so no, yugioh is not broken. its just a game that has to be handled with care when playing at the current metagame.

again, appreciating to hear your thoughts.
