I use the spiders for PvP and a friend on a flyer to pick us up to get to the bass that we are going to sneak into. No one is expecting a mounted Dino to come into there interal base area and start attacking them.
Also make great sniper mounts because they can climb up most surfaces, can walk in water, and are super small hard to be seen.
After the creatures replaced this many considered it useless now.to re-new this it would be nice if it had a full power climb,like megalania,maybe hav it be able to spin webs to trap creatures no-larger than a carno,to top it all off hav it spin webs around your base that produce silk and when wild dinos try to attack they get caught in the web.
Don’t underestimate these things. A dilo and an araneo set on turret mode completely blinds any would be attacker. Pair that with a raptor for the pin, and an onyc for megarabies and the armor wreck, that player won’t know what hit them.
