In naval terms, then dragons and other giant titans are ineffective, for similar reasons a walker wouldn't be efficient in modern warfare. Being big and giant causes more collateral damage, makes you slower, and gives you less magical support and range strength, which means if you have a line of a bunch of range-type shifters, the dragon or whatever is practically null.

Destroyers and the like replaced battleships because they could fire long-range missiles to hit precise locations, and cost less. Battleships were too big and too inefficient in comparison. Could take some damage, but a Destroy could fire a single missile and disable the ship without even sinking it, all the while being smaller and faster. Submarines could remain undetected and hit precise targets without anyone knowing, in their day.

Aircraft carriers could launch strikes against other boats from an even longer distance with better coordination and with more variety of weapons.

The big stuff is nullified by the new modern stuff. A dragon is like a heavily armored knight against a bunch of leather-clad against a bunch of ninjas with poisons and the like. Being a dragon is just being a giant punching bag.

And as for my app, I don't think I'll be joining because I've got a poopload of homework, and I'm tired and already relatively slow with my current roleplays. In addition, I can only really make big, good posts when I've got the proper inspiration, which I had at first, but not anymore.

And as for the self-insert thing, my characters are all somewhat like me. Not exact copies, but more so I have something that I _KNOW_. I'm not very good with being someone entirely different; every time I try writing a story, I feel like my characters are fake and stupid, and lack real personality. Having a basis similar to myself simply lets me have a much more realistic character, which I can change from there. Call me a crappy writer, I probably am.
