Bear - Nerf it's fiber gathering. Remove saddles. Reduce health.
Chicken - It's fine
Cow - It's fine
Bull - Buff it enough to make it the "lowest tier" of thatch gatherers. Allow saddles.
Crow - It's fine. Could even use an extra 'something', as currently it's just a "Put on my shoulder when crafting, ignore all other times" tame
Razortooth - This should be the crem de la crem of offensive tames.
Shieldhorn - Make it the "highest tier" of thatch gatherers.
Elephant - Increase health, at least higher than bears.
Giant Pig - Slight health increase. More players should be using these as shock troops
Giraffe - Make it the "mid-tier" of thatch gatherers.
Horse - Do not make this a passive tame. Speed is fine. Anyone complaining about it going too fast possibly has a terrible machine. Lower weight. Allow cargo/weight saddles.
Lion - All of the offensive T3 tames need a slight buff. Do not buff them so high that you make the Razortooth a joke.
Monkey - Fine. I like the idea of small secondary abilities that others have suggested.
Ostrich - Fix the dismount issue. I believe it's the same speed as the horse? If so, increase health, weight and damage slightly above the horse. Do not allow saddles.
Parrot - Fine. I like the idea of small secondary abilities that others have suggested.
Penguin - Give a small AOE insulation buff which also affects babies/juveniles. Multiple penguins stack.
Rabbit - I like the idea of small secondary abilities that others have suggested.
Rhino - Slight increase to weight.
Seagull - Fine. I like the idea of small secondary abilities that others have suggested.
Sheep - Changing fleece from hide to a fiber would make the tame a no-brainer. No brainers are bad in games, do not do this. Drastically reduce the amount of fleece given from harvesting a dead wild tame.
Tiger - All of the offensive T3 tames need a slight buff. Do not buff them so high that you make the Razortooth a joke. The Tiger and Lion need something to differentiate them more than a grab that's useless in PvP and a DOT.
Vulture - These are so meh right now that almost anything would be a good idea.
Wolf - All of the offensive T3 tames need a slight buff. Do not buff them so high that you make the Razortooth a joke. Allow saddles, which differentiates them from the Tiger/Lion. Reduce Health, Weight and Melee Dmg to compensate for this.
Cargo saddles - Make them actual cargo saddles. Remove the ability to put guns on them. Make the saddle a container that has 20% reduced weight for all resources (resources only). Weight on the saddle is counted against the tames total weight allowance.
NEW CREATION - War saddles - What the current cargo saddle is. Reduction in speed to any tame with it on.
