Well, since monsters are extremely vulnerable after the September 1st banlist (Chivalry, Chariot, BTH, all the rest), there had to be some way of compensating for that. The high attack of these monsters ensures that even if only one of them gets on the field and stays there for a turn or two, it'll inflict some actually relevant damage even though it doesn't kill anything. Remember, Blitz monsters can't swarm, so basically if you don't have one your opponent can push for more damage, and with the current state of the game dominated by high attack but often low defense monsters, most of these monsters are going to be in attack position to avoid taking massive damage versus a Blitz deck, and if Blitz monsters got removed then these guys can simply swing for massive damage back. That is in part the reason for the high attack stats of these monsters.
Doesn't Thunder die after a direct attack made with it by its effect?
As for Lightning, well... that was my intention. 4000x2 = 8000, and since you have to actually tribute a monster to summon him in the first place, that investment was deemed large enough to fit the power level of the card.
A one monster Tribute isn't exactly the biggest thing. What, with all these Treeborns and Special Summons running about, using one non-specific Tribute means that that monster can be summoned in nearly any type of deck. You could splash him in ANY deck (lol Zombie World deck), and so long as you have Monster Reborn, Call of the Haunted, or just any swarm mechanism, you can hit your opponent for massive amounts of damage.
Turn 2, you can just revive him and attack through a monster and you're more than likely to be at least 6000 points up on the enemy. Then, he doesn't even get destroyed by his own effect, so you have a wall. His non-destruction by battle effect makes sure the enemy still has a monster to attack next turn, provided they can't get rid of it themselves. With that one monster in your Deck, you don't even need the rest of the archetype.
Sure, you can say he's got a lot of weaknesses -- Royal Oppression, Dimensional Prison, Bottomless Trap Hole, Torrential Tribute, Mirror Force, Solemn Judgment, etc. but his sheer force is just... Staggering. That, and that list is applicable to every monster in the game. He doesn't have a blaring weakness other than versus himself in a mirror match while he's in defense position (granted, he one-shots you if the foe has Magical Cylinder or Dimension Wall).
He's just too easy to get out... I'd suggest making him at least 2 Tributes and making him unable to be Special'd... After that, I'd suggest cutting his ATK (even the most powerful of monsters with the Piercing effect only has 3000 ATK and doesn't have his double damage effect) and then removing the double damage effect altogether... Reason below:
It's a problem with any sort of effect that doubles battle damage taken. Double is a LOT. It's the same reason why we don't halve the foe's Life Points with burn cards. It's A LOT. There are only three cards now that double battle damage taken: Canyon, Stone Statue of the Aztecs, and Sauropod Brachion. All of them only work when you are attacked -- meaning, they actually give the foe a chance (whereas, Lightning just pops up, wreaks havoc and laughs) -- Canyon is a Field Spell, so it lacks any form of surprise. Stone Statue has poor stats and has no other use other than that effect (which diminishes his play once he's out). Sauropod Brachion requires two Tributes to set (or one if you use a Dinosaur) and it's rare for Tribute cards to be set anyway, so it's obvious which card(s) it could be. All these cards CAN OTK just like Lightning, but since they rely on your enemy, they aren't nearly as viable.
Just... No.
edit And alternative is to make him only be able to be Summoned if you have a certain (a pretty high) number of "Blitz" monsters in your Graveyard with different names. That makes sure you can't splash him in any deck. I'd still suggest making him unable to be Special'd, though.
