This dino is by far my favorite. If you can manage to find 3 120 allos you will be close to unstoppable. When you have 3 allos( doesn't matter what genders) the highest level will be considered the "alpha", this means the alpha can do bleed affects which causes damage over time as well as slows you down temporarily. When getting a pack of allos or a allo the only stats that ever need to be pumped is stamina, melee damage, and movement speed. Hope this helps! 😄
If you get a pack of at least 3 good leveled allos you can kill anything except for obviously Titan and giga our tribe has a few with 14k HP and 400 melee and with 3 of them we can easily take out alpha rex and other strong dinos, also they are a lot faster than most carnivores and not to mention the highest level gets an "alpha" boost where it can do the gash attack they do in the wild where they slow you down and make you bleed
The highest level Allosaurus will become an Alpha if at least one other is nearby; you do not need 3 to gain the Alpha Bonus.
The best way I find to breed Allo's is to find a pack with 1 150, kill off the other two and tame a 150 Allo. Do this for 2 150 Allosauruses and you can breed a nasty army of these things. You'll be able to take on Rex's like they're dodo's. Wyverns make for east kills, too. Just watch out for Alpha's.
The only thing a good pack of Allo's cannot take on, is a wild Giga.
Allos have the speed of a carno and the strength of a rex; a well-rounded creature to go for. In packs of three or more, the highest lvl allo will become the alpha (the one with the cheeto dust cloud), which can do bleed damage that deals DOT and slows down a target. Definitely recommend mass-taming for PvP.
In a pack, Allos have the damage of a Rex with the speed of a Carno, paired with the Alpha bleed attack they can devastate all but the toughest dinos. Just make sure they don't get stuck and to level health as they are a bit squishy at first. You couldn't ask for a more versatile carnivore.
