I'll admit that being able to expect every nine shots from warriors to strip a hull point isn't too shabby. I'm still not sold on them being the best troops in 40k, but I will put them to top tier. The lack of weapon options can lead to easier movement decisions, which might be an advantage in tournament play with limited time. "You're paying a premium for guns and a save which are only marginally better than their counterparts." I would say that those are points well spent, especially in the mirror match up. Gauss blasters shred warriors, but plink off immortals, though both are able to stand back up.If you're going for durability in troops, you can do a lot worse than the ghost ark. Would you mount up initially or have the warriors near the ark so that they present two targets and the warriors can benefit from the ark? Night Scythes are just awesome, next.
What would you put as better? Guard are cheaper, but they suck. Purifiers are amazing, but cost twice as many points per as warriors so that's a bit out too. That leaves us with either the base CSM squad, which is rife with options, or a grey hunters squad, which "suffers" from Ld 8. In either case, both squads lack the innate flexibility of warriors//immortals without spending additional points, or sacrificing points.Immortals proved their worth at my last tourney. They ruin anything's day except marines pretty steadily. And even then, the only way marines outshoot them is if they're Sternguard or Purifiers. Both of which are significantly more expensive per model than the immortals and lack the resurrection, meaning i'm more likely to hold onto my points, even when I do fail my saves.I usually kept the warriors mounted until turn 4 or 5. It's open topped so you don't waste the shots you pay for and don't have to give up hull points to replacing models.And yeah. Invasion beamers > hover mode.
I wouldn't say guard suck when compared to their points cost in other troops, but that's a different point for a different time. I would put Grey Hunters above Necrons, but it's hard to beat that. It's mainly for their melee ability and their higher maximum ability at either anti-heavy infantry or anti-tank.
