So... this is the best tip (no offense) in scorched earth these are the most useful dino EVER, so when you want to get wyvern eggs you can get eggs with a pteradon or tapegera and grab an egg and run off but use Dinosaur gates and switch off you flyer to a galli and cryo your flyer and run away on your galli. BAM you got a wyvern egg with you cool dude Galli bro.
Galliminus is the best dinos for traveling and scouting, their base speed is epicness, just bump up the weight and stamina and you got a traveller dino! You could get mastercraft saddle just by doing the pursuit raptor hunt.
Max stamina and movement speed for great trolling fun. Have a friend sit on the back with tranq darts and longneck. Run up to people, dart to the head, go "meep meep" and zoom away. Watch the rage in global chat and giggle.
