I just need to get something off my chest and. Emma Frost is a powerful telepath, one of Marvel's best. She is a smart woman, from doing business, to teaching students and helping lead the X-Men. So Emma has a lot of positives to her as a character and what some love is what others hate. But to be honest, I don't see much growth left for her as a telepath. She is already powerful, already skilled in that art. So my biggest problems with the character, my personal opinion of her greatest flaws are her diamond form and lack of combat skill.
Her diamond form as quoted by Emma is "blessedly indestructible." We know it is not, but her durability in it is pretty high. Emma is bulletproof, has tanked shots from World War Hulk and eventually gets planted in the ground and still didn't break just to get taken out of the fight, blasts that sent her hundreds of feet from Bishop, hits from a highly amped and pissed off Sebastian Shaw, jet crashes, Genosha, and even recently a blast from the Dreaming Celestial's head when controlled by Mr. Sinister among other things. Her flaw is commonly known as her shatter point and even that took required circumstances. Aside from her one flawed spot, and recently lost an arm due to one of the Dreaming Celestial's probes. Considering one of the probes blasted Colossus across San Francisco, ripped a hole in his chest and cracked him even further along the torso which you don't see happen often at all with him, it showed quite a limit to her diamond form.
Now this is one of the big flaws, we look at her durability and compare it to her strength. According to handbooks, Emma is a supposed 2 ton limit and based off feats, some peak humans and people lower than that have better strength feats. She has a high end durability, but her strength is terrible. She is one of the X-men's most durable characters so she has the potential in that form to stand up to heavy threats, but her strength is severely lacking which hinders that. I'd like to think Marvel should at least make her a solid 10 tonner.
Another problem Emma has is a lack of combat skills. This could obviously be solved and used in conjunction with her diamond form. In comics, when characters lack a strength or speed against bigger, stronger and faster threats, they give said character a high skill level in combat to compensate or they have a fancy weapon. I know Emma has her telepathy as her primary offense but there are times that her telepathy can't work and it isn't unlikely more characters will develop higher resistances to telepathy or new characters will be made that are immune to it so she has her diamond form as a backup. Now Emma isn't a terrible fighter, but she is by no means a master and is only capable at best and has basic defense training. She did manage to fight off lizard creatures without powers, held her own against Bishop and Sage in diamond form before getting blasted away, and managed to hold off a lizard Gambit and Wolverine for a brief time.
She doesn't have to be Psylocke in terms of skill but she could be made a better fighter and combined with diamond form, she could be formidable in those confrontations when telepathy isn't going to work. The diamond form should technically add some weight to her blows and if she straightened out her fingers she could use her hands as dagger like weapons. Since Emma isn't the fastest character either, instead of just being a new Wolverine and tank shots constantly to get close, she could use her new skill level to dodge attacks and come in for a good punch or kick or finger stab/slash which I think could work. Scott is good fighter, he should show her a few new combat moves, or take a lesson or two with Psylocke. Emma has the resources and options at her disposal. All it needs is Marvel to get a little creative and realize it.
So that's my little rant on the subject. Some might say it isn't Emma to fight like that, but if it really wasn't she wouldn't have stood up to Hulk like she did, she would have left with the Celestial attacking, or the Vampires etc. She does fight when she has to and is smart enough to cover all her bases. I just hate that she is either a proverbial glass cannon or an adamantium water pistol. She is a powerful and skilled telepath in her human form but can be easily killed. In diamond form, she is just hard to put down without a knowledge of a shatter spot, but is next to useless when confronting a physical threat. I know she is good at mingling her abilities but like I said there are times that isn't going to cut it. Responses, comments, criticisms are always welcome.
