These are a PAIN to tame. I found a lvl 90, and it latched on to all 5 of my voidwyrms. It was at 93 percent. I needed more themes to give it. I fly back to base, any grab my wolves and argie. It latched on to a wolf, and started attacking everything. But it was tamed! After 3 attempts. But an aggroed paracer comes and stomps it to death. 30 seconds after taking it and dead.
I'm finding that on servers with higher Wild Dino levels, 5 Brontos are not enough for max efficiency. And since Noglins will eat 5 dinos before they lose efficiency, they are impossible to get max efficiency when taming them.
Use brontos or voidwyrms only for max effectiveness (five individuals), they must be a higher level than the noglin by a certain percent, not sure what that is. If a noglin is over 150, max effectiveness is currently impossible.
