Don't worry, everyone will have different opinions, nothing wrong with saying them, especially as I specifically asked for them.
I'll go from the start: I only own Scatterlasers for my War Walkers and although I could order some bits from Ebay, the thing is, I love Scatterwalkers. I've used them for years with the same setup.And I'll tell you why:
Scatterlasers are one of the few options I consider valid for War Walkers. Others include:
Starcannon/Scatterlaser - great if you don't have Farseer support or are playing in a
MEQ heavy environment.
Brightlance/Brightlance - great
AT platform, but usually it's an overkill. If I used this combo, I'd probably use a squad of 2.
Problems: Much less of a threat except vs anything that is <T4 and sporting 2+ save, or
AV 13+. Easier to ignore for a lot of armies than Scatterwalkers, and a priority target for armies that have a lot of 2+ saves or AV13+ vehicles.
Shuriken Cannon/Shuriken Cannon - cheap, effective, but expensive for 24" range guns on AV10 open-topped walkers.
With all of those other options, their targets are more specialized, making them lose effectiveness as soon as they run out of their prefered targets. That's also why I'm vehemently opposed to mixed weapons, except the
SL/
SC combo, since you're the same S, same range and you gain the benefit of laser-lock. In other cases, you're always paying for something you don't get, whether it's range, strength or
AP.
With Scatterlasers, you'll always have something to shoot. In fact, in about 5 years I've played with my Walkers, I never ran out of targets for those 24 S6 shots. There's just so much versatility in there that I'm incredibly biased towards this loudout.
Second problem with exchanging a Falcon for another Serpent is what will I put in it? I'm really not a fan of DAVU. I'm paying points for something that will probably never fire. Plus, I'm of the belief that to really utilize a Wave Serpent, for which you're paying for that 12-man transport capacity, you should use a full squad. The different between 5-man squad in a Serpent vs a 10-man squad in a Serpent is only 1/4 of the points increase of the whole thing for 1/2 effectiveness of the squad.
As for Warp Spiders, well, I'll playtest it, for sure and see how I like it. I'm usually running a 10-man Spider unit, but what I found is that with them, I usually lose a few to random enemy blast scatter or I don't manage to hide just that one or two behind a ruin. It's a squad that really likes to dance just along the edge of the dangerzone and a full squad seems too unwieldy to me. Ideally, I'd use 2 5 or 6 man squads, but there's no room for that in my
FA slots. So we'll see if I'll stick with the Exarch or just go with 10 regular.
