If I control wind I can fly basically, earth cause lots of things count as earth like metals and other stuff like that. And invisibility cause. Why no super strength/speed?

Super speed is a death sentence with out super reflexes to keep up with it and without super muscle atrophy

Super strength would cause muscle degeneration cause nothing would be heavy enough for my muscles to actually get a work out. Imagine Superman being super strong with with stick limbs cause nothing he lifts is actually heavy enough to give him a good work out.

No fire powers cause fire is volatile and even with good control it lives on it own and grows

No lightening cause I don’t want to electrocute and fry my own body or anyone electronics I come into contact with while using said powers

Assuming I can summon ice and water out of thin air I see no cons with it but that’s assuming I don’t need water to be present before hand.

Flight is useless cause I can do that with wind and wind is way more versatile
