Chocobo Help

Okay, I'm not new to to the but need help understanding this if anyone know ?
My chocobo is a healer and I'm a tank my main tank is Paladin lvl 60 and my chocobo lvl 11 when I use my paladin my chocobo has 10900 HP and heals between 1900 to 2400 hp.
Lately I decided to pick up my warrior at lvl 50 only to be easily killed by normal monster out on the field. Initially I though my warrior sucks but after I gear it up there wasn`t much improving.
Only after that did I realize the problem my chocobo sucks.
When I turn to my warrior my chocobo life is cut down to 2000 hp and the healing goes down to 300 hp.
I know that the chocobo scales down to your lvl my there should not be this much of difference in 10 lvl.
Is this normal or is this some kind of bug ?

There is a monumental difference between level 50 and 60 actually. The chocobo can be considered on par ilvl-wise to commonly crafted gear of that level. For level 50, that is NOT the ilvl 115 HW gear, but the ilvl 50 gear from ARR (The same applies to mob difficulty too, except level 50 mobs in HW areas ARE ilvl 115, while open world level 50 mobs in ARR are ilvl 50). At level 51, your chocobo will be ilvl 120.

Frankly as a war you shouldn't have that much of a problem killing higher level mobs. Comboing bloodbath with beserk, defiance off, use CDs etc... should get you through single mob encounters easily - use defiance if you need the extra hp, thrill, use inner beast as needed.

I was soloing(without a chocobo) lvl59 hunt marks at lvl 53. It was close but I did it - died a few times until I figured out how to handle things and such. So really shouldn't have much of a prob with anything lower level at all - unlike a PLDs death by a thousand paper cuts...
