It's a little slanted to compare FFXI DRG at 11 years to FFXIV DRG at 7 months. During FFXI's first year (level cap 65? 50?) DRG was a lot less jumpy, too. And calling the wyvern was only a 2-hour ability for over 5 years.

We're probably getting new abilities in the next patch. Yoshi-P has in the past mentioned not dragons but sort of dragon-like abilities in the future. So maybe more jumps and maybe a dragon breath ability as soon as patch 2.2.
