If you think they have too many hps you should find some in era evidence of how many hps they should have. I would guess p99 is close to the values on the wiki
http://wiki.project1999.com/Pet_Guide#Enchanter_Pets
If you think those values are wrong then find evidence to support that. I would think if you spent some time with the web archive you might find an in era table of enchanter pet health somewhere. Otherwise you are just asking the devs to blindly reduce hps, how much should they be reduced? 5%? 10%? 30%? There is really no way to turn the vague quotes you have into a number.
Personally I feel like they are fine at least up to 24 as they fit with my memories from playing in 1999. Many people back then didn't know how to tell if they had a max level pet so a lot of those comments are just a function of how much worse low level pets are.
