I personally own 2, I used to have a 3rd but it was unbuilt so I traded it away, and yes I love them and include at least one in most of my WoC lists. That doesn't stop me from objectively saying that WoC should either be toned down in close combat or not allowed to have excellent shooting like marauders or hellcannons. I'm not saying that WoC is totally broken, but it is in the top 3 of all my armies and is the easiest to win with while not needing tactics.
Alternatively what units will roll our saurus warriors over like they were nothing? Other than monstrous cavalry
*edit* I feel like a complete newbie here, but Protector comes off as a master of saurus warriors so knowledge must be obtained :3
Thanks guys, I really enjoy being able to share my experience with everyone, for a long time I've only played locally and didn't really know a lot of lizardmen players. Now that I've had the time to come back online here, it felt like there was this whole consensus that lizardmen are under powered and things like saurus are not competetive, which is the opposite of all my experience, so I've been on a personal play testing crusade to vet our lizards against some of the toughest things this forum has mentioned.
So here are some units I will try to keep my saurus warriors away from, this is not an exhaustive list and a lot depends on the situation, but generally saurus warriors have unfavorable matchups against these units.
Hellpit Abomination - This thing eats saurus alive and won't take wounds easily, it is probably one of the only units in the game where I will try to avoid at all costs getting saurus warriors into a fight with.
Chaos Knights with enscorcelled weapons - These suckers have the strength to kill saurus after the charge and still have a 2+ AS against us, so they will do about 5-6 wounds to every 1 we do back, this isn't the end of the world but they can chew through 20 and less sized units and still keep their points.
Savage Orc Big Uns - Too much damage in the first round, this combined with the fact that they are the same points as saurus and generally fielded in large groups means it will be very hard to stick around after the 1st round. Never engage in building combat with them unless they have lost their frenzy!!!
River Trolls - Hard to hit and hard to wound, it's not that they will walk all over us but we take a lot of damage for not much in return, they win the exchange almost every time.
Chaos Warriors Nurgle/Khorne - I won't say don't engage, but plan to help your saurus out on these matchups because you want to come out keeping your points from the unit while taking his. Do not engage Khorne warriors in a building combat unless they have lost their frenzy.
Stormvermin - I don't actually hold my saurus back against them, but remember that point for point you will lose the exchange and you need to have a plan to finish them off or help your saurus shut them down, with a simple buff or double charge they are easy to deal with.
That's all I can think of for now, I'm sure there are more but for me everything else is fair game. I focus on winning deployment and then I go after 2-3 key matchups during movement, this allows me to control about half the combat during a game heavily in my favor the other half is lower points and/or delaying until I can bring more units into the fight.
