sod balance! they're called Gifted for a reason - you don't see people whining at Colossus for being bulletproof (oi mate, take your armour down so we can hit you)

Add a mandatory flaw if you want more balance - something like the hostility aimed at Warforged in certain places (or the Xmen for realz). Roleplay it to the hilt, you're the next step on the path to power and people fear you. Do you pimp slap them back into their place, lowly peons that they are, or work to gain the trust of the silly plebs that so fear and despise you? Hell, people distrust wizards, sorcerers and warlocks just for figuring out how to conjure fire at their fingertips..they'd freak out if you could do it completely naturally

see Emma Frost if you want to introduce a balance to the Armoured gift - made of diamond but has a structural flaw. Give a vulnerability to sonic damage. Give Feral/ Sense enhancement Gifted the same vulnerability (Hulk almost kills Wolvie by clapping his hands together) etc. If you're made of steel, hey Heat/Chill Metal suddenly becomes a problem: your skin just sloughed off!
Elemental Manipulation - make it so you're not immune to your own powers, singe off your own eyebrows every so often
yadda yadda yadda
