Poor writing.

Iceman's powers were pushed to their limit while possessed by Emma Frost, who used Iceman to discover the fate of her Hellions. During this time Iceman was able to control all forms of moisture, freeze fluids inside people's bodies, travel as a liquid, solid or gas. Not even the combined might of the X-Men Gold team was able to stop Emma Frost in Iceman's body.Following this Bobby confronted Emma about how she was able to use his powers so effectively and while together they make some initial progress but she refuses to train him.[53 ] Instead he turns to Storm because they share similar elemental powers and she agrees to tutor him.  Ok, what the hell? Emma Frost is a damned head instructor for the X-Men, but she refuses to teach Iceman? Is this true? Does no one on the X-Men give a crap?   When Emma controlled him, not even the entire X-Men gold team could stop Iceman! So he could be THAT powerful, and Emma just flat out refuses to aid him? When this could have saved lives during the entire Second Coming act (and countless others)?

There really is no good excuse. Cyclops needs to make her train Iceman. And although Iceman doesn't really want to be a superhero, he still needs to contribute to the survival of his race.

He's not mature enough to handle that kind of power?

It's Emma, seems exactly the type of nasty spiteful thing she would do but then again that's just my perception of her.

I'm betting he'd adopt that required level maturity to save his friends and teammates. 

Because he can already do all that currently

That's even more frustrating. 
 
That means Iceman is currently a team-buster, and can singlehandedly take down a team like Gold Team. Yet he's consistently taken out of the picture (like having a Nimrod burn him into medical watch: LOL) or never involved from the start. Sigh.

Its not that she won't and he probably really doesn't need her to now anyway (Iceman made a LOT of progress by himself under Mike Carey), and she's not the one who gets to decide to aid him anyway. Its all the writers in this scenario. Power regression or being lazy. I mean, its like, why won't Iceman teach Iceman how to do in Uncanny what he did in Legacy? Can we blame Iceman?  
 
Plus like another poster mentioned, some of that info isn't worded the best. I thought the Nimrod thing was okay, I mean, it could have been more specific and detailed, but my assumption was that the plasma attack was some sort of neutralizing agent that didn't actually burn him, or have the intent to burn him (unless maybe it was super, ultra heated in ways that can't be matched by current technology) but yeah, maybe it was working at neutralizing his powers/and or attacking on a sub molecular level (or basically just being a deus ex machina type attack, which is sort of okay here, because they are from the future and should possess technology that makes no sense to most people today yadda yadda) I mean, maybe, if Iceman was skilled and experienced enough, he could have snapped his own arm off and then reformed it... we have seen him blown up and return, but I haven't seen him consciously destroy himself to return (and maybe that's something that should stay in place for the immediate future)

Emma is just a bitter English shrew who likes to manipulate and hurt people verbably and emotionally!! The only thing she is good at (besides the obvious) is being heartless!!

I really hate posting scans, but it seems like many people never did their research, and like I said the summary here is incorrect, and it would be nice to set the record straight?

She's not bitter. Nor a shrew, nor even English for that matter. Yes, she manipulates, but it's for the greater good. It's to HELP people. So please actually do your research on a character before spouting off statements that couldn't be more inaccurate.

It's Emma, seems exactly the type of nasty spiteful thing she would do but then again that's just my perception of her.

LMAO @ all the Emma shade. ^_^
 
...IMO, Iceman couldn't handle controlling his powers at that exteme of a lvl yet....and I don't think Emma could properly teach him to do all that w/ just a few psy sessions. If she were that powerful, almost all the x-men would be omegas by now! So, no. lol 
 
   .....and we know how many of y'all hate on "ridiculously overpowered" mutants. #Jean *eyeroll*
