You make some good points.
Thank you!
I'm still not opposed to using the suit in battle. After Iron Man i don't think it will look goofy and could potentially look outright awesome. My feeling is make it something he builds progressively and only uses in the final conflict.
1) It would look like an Ironman rip off. I know it isnt, but does the GA?
2) As i said, i dont see why Lex would expose himself to such danger when he can use others to do his dirty work.
3) I believe that Lex considers this beneath him. He calls Superman a powerful brute, so trying to match him in brute strength makes no sense.
4) Lex cant be as fast or powerful as Superman, so unless he is beating up a K poisoned Supes, there wont be much fighting. Supes will tear it off him. Either way it wont be impressive because the fight will be over very quickly in both cases.
I think you could approach it as they did Ezekiel Stane (if Iron Man 3 doesn't use him). He essentially made himself into a weapon but also used a suit.

No matter how high tech or evolved, even with Extremis, the Iron Man armor is still a guy in a suit, if you get between the man and the suit you can undo it. So Stane doesnt need a suit. Thats the difference. Thats what we start to see, the future of Iron Man is that theres no gap between Iron and Man. Its one being and Stane is quite literally evolving himself and people who pay him as we see in the books opening.
I have started reading this a few times but always drop it after a while. I saw a black suit beating up Ironman in that wiki page. Is that him?
Anyway, this way they would be giving Lex powers... I just dont feel it. It would be like the Joker learning martial arts and fighting Batman. Its... completely off character for me. I prefer the suit a 1000 times over this.
Also, Lex believes in humanity and its purity and is distrustful towards aliens and metahumans. I think its completely off character for him to become one. Comics need to print a new issue every month, so they leave no stone unturned (not to mention that there are millions of bad comic book writers out there) so why would a movie trilogy jump right into this when there is so much more to Lex? Here:
Would be interesting if in the final battle superman is truly outclassed by luthor and now he's the one who has to use his head to defeat luthor. Illustrating the point that the true fall for lex was that he began relying on brawn over brains.
Superman is often found in situations when he has to use his brains to beat more powerful opponents or opponents who have gotten the upper hand of the battle. Why bring Lex in something where he doesnt belong when there are other villains for that? Superman can use his brain to figure out Lex's plan or beat his superpowered thugs, not Lex himself in a brawl.
